Good god go read a text book then come back. At least have the basics down before you ask silly questions.

Time is one of the most difficult concepts in the universe. Stephen Hawking grappled with it and barely made a dent. The forwards / backwards question is explained by entropy. The glass falls off the table and breaks. It never reassembles and jumps up. Whether time is running both ways and we only experience one, or it really runs one way is a problem that cannot be answered. Studies at the quantum level only make the issue more confusing.
Scientists (the use of the derogatory "evolutionists" shows your lack of character) do not know the origin of time. Time may not be an effect, but the differential between cause and effect itself. Lack of understanding of its origins, does not impede its measurement. The Earth is slightly older than 4.5 billion years and the universe is 13.7 billion years old, all based on repeatable measures.

About 15 billion years ago.
Note that I really do mean that time itself does not extend
indefinitely into the past. It is not simply the case that
15 billions years ago the universe began, and before that
there was no universe. I mean that the question of time before 15 billion years is a bit like dividing by zero. It is not defined. The assumption that time is a continuous flow against which we measure events turns out to be false. Time and space and matter are all part of the same structure, and that structure does not extend indefinitely into the past.
That is, assuming that "eternity past" has something to do
with duration of time into the past, it turns out that there
is no such thing as eternity past.
This answer was not obtained simply by logic. Logic is
nothing more than a disciplined way of reexpressing your
initial assumptions.
It was not obtained by faith.
It was obtained by the usual scientific tools of observe, theorize, experiment, test, repeat indefinitely. The conclusion is, like anything else we know, never absolute. We simply do not have direct access to perfect knowledge. As far as conclusions go in science, the conclusion of a strict bound to time itself in the past is pretty solid. By way of contrast, there is not definite conclusion on whether or not space is open or closed: that it -- unbounded and infinite or bounded and finite.
These ideas are not easy to explain. Generally, if the universe is closed then it has a finite extent, and a finite number of particles, and a finite future: time itself is bounded in past and future. If the universe is open then it has infinite extent, and an unbounded number of particles, and time will persist indefinitely. One of the puzzles of modern cosmology is that the universe appears to be nears as dammit to "flat"; hence the question of being open or closed is still an open question.

Where did god come from bro? Surely something as complex as god couldn't have just "been there"...wouldnt he need a creator as well?
I will admit it, i dont know when time persay began...although the big bang happened about 12-14 billion years ago. I am not sure where the energy came from, and I probably will never find that out. But that doesnt mean i create some imaginary god to compensate for that. I look for a practical reason.

You complete lack of knowledge of both the physical and biological sciences is truly impressive.
Evolution is about biology; it is the foundation without which every life science – including medical science – is false.
And, why does time need a beginning? What even makes you think that time is real? It may be nothing but a product of the way the human mind organizes and understands discrete events in space, thus reducing the space-time continuum to just the space continuum.
You do not understand one word of my answer, huh? That is because you skipped all of those math and science classes in school, huh?

Please tell me you're joking... 'time' is just a concept that humans use to describe the passage of events. It's not an action or a reaction, time would still pass regardless of anything.
As time is a human concept of the passage of events, not the undoing of events (which is technically impossible) and the word "forward" means to progress onwards, not backwards.
It's not relevant to evolution, it's completely irrelevant. Evolution isn't about the "creation" of time, it's about the effects time has on species as they develop. The origin of time as a concept is mankind.

You ask the ultimate question. When did time begin? Science can only estimate. But certain measureable facts remain.
The half life of carbon is constant. It's electrons orbit it's nucleus like a clock, but millions of time a second. It's large isotopes have hundreds of electrons. Over millenium the law of entropy causes their orbits to weaken. The electrons fall away. Science can measrure this loss of electrons in carbon isotoptes.
Time as a constant is entropy; deterioration of matter. As in the half life of carbon isotopes.
This loss over great periods iof time is constant and predictible, mathematically. This is how scientists know bones and rocks are hundreds or millions of years old.
We know how long it takes carbon isotopes to waste away to nothing. What we do not know is when they began to exist.
Science however by the mathematical fact of carbon dating can prove that the universe is billions of years old.

While time is indeed a part of the evolutionary process, your question has nothing to do with evolution.
You might investigate entropy--the forward motion of time is actually the increasing disorder of the universe. Time can't go backwards because matter and energy can't become more ordered.

No this is not relevant to evolution because regardless of how it came to being it still has the directional properties that it does and evolution still has evidence for it, regardless of whether a god exists or not.
You might as well have just asked how the universe came into being because those two are indeed linked and essentially make the same point you are TRYING to make.

Time may not have ever begun. Time and space could both be infinite. You do think there is such a thing as infinity do you not? If not. Then tell me this. Where does a circle begin and where does it end? solve pi to the exact decimal. Can't huh? That's infinity. I don't know the answer to your question, just possibilities. There are others. We're still working on it. Stay tuned.

You have heard the the fabric of space is space/time and physicist think that on the quantum level time can run in any direction. You are thinking in that primitive, Bronze Age manner again, where thing need beginnings and endings. Those are man made concepts.
