Past Life
The first measures of time were nature based. Knowing the length of each season helped nomadic tribes travel to lands optimal for survival. The phases of the moon gave universal and accurate scale. But time has developed into an essential entity of existance that runs our lives and is seldom questioned.

The following information has samples taken from Wikepedia.
Time is a component of the measuring system used to sequence events, to compare the durations of events and the intervals between them, and to quantify the motions of objects.
Time has been a major subject of religion, philosophy, and science, but defining it in a non-controversial manner applicable to all fields of study has consistently eluded the greatest scholars.
In physics as well as in other sciences, time is considered one of the few fundamental quantities. Time is used to define other quantities – such as velocity – so defining time in terms of such quantities would result in circularity of definition.
An operational definition of time, wherein one says that observing a certain number of repetitions of one or another standard cyclical event (such as the passage of a free-swinging pendulum) constitutes one standard unit such as the second, is highly useful in the conduct of both advanced experiments and everyday affairs of life.
The operational definition leaves aside the question whether there is something called time, apart from the counting activity just mentioned, that flows and that can be measured. Investigations of a single continuum called spacetime brings the nature of time into association with related questions into the nature of space, questions that have their roots in the works of early students of natural philosophy.
Among prominent philosophers, there are two distinct viewpoints on time. One view is that time is part of the fundamental structure of the universe, a dimension in which events occur in sequence. Time travel, in this view, becomes a possibility as other "times" persist like frames of a film strip, spread out across the time line. Sir Isaac Newton subscribed to this realist view, and hence it is sometimes referred to as Newtonian time.
The opposing view is that time does not refer to any kind of "container" that events and objects "move through", nor to any entity that "flows", but that it is instead part of a fundamental intellectual structure (together with space and number) within which humans sequence and compare events.
This second view holds that time is neither an event nor a thing, and thus is not itself measurable nor can it be travelled.
Temporal measurement has occupied scientists and technologists, and was a prime motivation in navigation and astronomy. Periodic events and periodic motion have long served as standards for units of time.
Examples include the apparent motion of the sun across the sky, the phases of the moon, the swing of a pendulum, and the beat of a heart.
Currently, the international unit of time, the second, is defined in terms of radiation emitted by caesium atoms. Time is also of significant social importance, having economic value (time is money) as well as personal value, due to an awareness of the limited time in each day and in human life spans.
In general, the Judaeo-Christian concept, based on the Bible, is that time is linear, with a beginning, the act of creation by God.
The Christian view assumes also an end, the eschaton, expected to happen when Jesus returns to earth in the Second Coming to judge the living and the dead. This will be the consummation of the world and time. The Christian view is that God is uncreated and eternal so that He and the supernatural world are outside time and exist in eternity.
Ancient cultures such as Incan, Mayan, Hopi, and other Native American Tribes, plus the Babylonian, Ancient Greek, Hindu, Buddhist, Jainist, and others have a concept of a wheel of time, that regards time as cyclical and quantic consisting of repeating ages that happen to every being of the Universe between birth and extinction.
The Vedas, the earliest texts on Indian philosophy and Hindu philosophy dating back to the late 2nd millennium BC, describe ancient Hindu cosmology, in which the universe goes through repeated cycles of creation, destruction and rebirth, with each cycle lasting 4,320,000 years.
In contrast to ancient Greek philosophers who believed that the universe had an infinite past with no beginning, medieval philosophers and theologians developed the concept of the universe having a finite past with a beginning. This view is not shared by Abrahamic faiths as they believe time started by creation, therefore the only thing being infinite is God and everything else, including time, is finite.
Time as 'unreal'
In 5th century BC Greece, Antiphon the Sophist, in a fragment preserved from his chief work On Truth held that: "Time is not a reality, but a concept or a measure." Parmenides went further, maintaining that time, motion, and change were illusions, leading to the paradoxes of his follower Zeno. Time as illusion is also a common theme in Buddhist thought, and some modern philosophers have carried on with this theme.
However, these arguments often center around what it means for something to be 'real'. Modern physicists generally consider time to be as 'real' as space.
It is generally accepted that, time appears to have a direction. The past is seen to lie behind us, fixed and incommutable, while the future lies ahead and is not necessarily fixed. Yet the majority of the laws of physics don't provide this arrow of time.
Time travel is the concept of moving backwards and/or forwards to different points in time, in a manner analogous to moving through space and different from the normal "flow" of time to an earthbound observer. Although time travel has been a plot device in fiction since the 19th century, and one-way travel into the future is arguably possible given the phenomenon of time dilation in the theory of relativity, it is currently unknown whether the laws of physics would allow time travel to the past.
A central problem with time travel to the past is the violation of causality; should an effect precede its cause, it would give rise to the possibility of temporal paradox. Some interpretations of time travel resolve this by accepting the possibility of travel between parallel realities or universes.
Theory would point toward there having to be a physical dimension in which one could travel to, where the present would be present at a point fixed in either the past or future. Seeing as this theory would be dependent upon the theory of a multiverse, it is uncertain how or if it would be possible to just prove the possibility of time travel.
But what of time travel to our past lives. Do we need to get into a scientific machine and defy universal law? Research would suggest otherwise. Countless experiences have been documented in controlled environments.
Information has been retrieved from past life regression sessions which was previously unknown to the subject and later proven to be historically accurate.
Just as a psychic can relay specific information to a person to prove a connection to the spirit world, that same information would mean little to society in general. A past life regression can be viewed in the same light. Specific information to the individual can provide long sorted answers to complex questions or relevant insight into current behaviour patterns. The same information would mean little to another. A past life regression experience is subjective. And nothing rings more true to the person, even if science dissagrees.
There are Many Videos on YouTube that explore the concept of past Lives. Admittedly, you have to sift through the junk, but listed here is a Past Life starting point.

From Reincarnation - The Vedanta Philosophy.
Almost all of the poets, ancient or modern, profess it.
Emerson says in his essay on Experience, "We wake and find ourselves on a stair. There are stairs below us which we seem to have ascended; there are stairs above us, many a one, which go upward and out of sight."
William Wordsworth says in 'Intimations of Immortality:', "The soul that rises with us, our life's star, hath had elsewhere its setting, And cometh from afar."
In Dryden's Ovid we read: "Death has no power the immortal soul to slay, That, when its present body turns to clay, Seeks a fresh home, and with unlessened might, Inspires another frame with life and light."
Similar passages can be quoted from almost all of the poets from different times of different countries.
