Let's say we went back in time to the beginning of the universe and everything is created in exactly the same way. Then the Earth is formed and it revolves around the sun in the same way, but now everything is randomized. Would the world be exactly the same as it is now? That is to say that is it by some sort of destiny that we are here or rather by random chance of one in a billion odds?
More specifically, would all life require DNA to reproduce? Would the same human inventions be invented at the same time? Would computers use a non-binary system? The possibilities are endless, or are they?

This question was posted under philosophy, I'm curious what different answers I'd get from "philosophical" answerers verses "scientific" answerers

You're talking about the domino effect. If all the matter in the big bang were packed exactly the same way again, and if all the energy was released in exactly the same way again, would the results be identical? Good question...
My thought is, if you *could* rewind everything back to the big bang, and let it play out again - yes, I think it would be identical.
Think of a fireworks explosion - or a hand grenade. Two identically made units probably would *not* have the same effect, because of outside forces - wind, air pressure, maybe landscape, back-blast effects, etc... But the Big Bang, by definition could *have* no outside forces. So... given two identical situations, I'd say the chances are good of identical outcomes.
IMHO.

Let see=We have historical record indicating existance of Humans to be about 5800 years from the Semetic calendar.
We substract that from 5 billions years that would bring you back into a few microseconds of Heavenly Time(time relative to a Heavenly frame of reference).
Probablibalistic formation is not random. Since probability is a forced function. That means its a dependent function. Hence we cannot talk about the Universe and biological life as being randomly formed.

The world would be completely different. Mutations are random events. Survival of individuals is largely based on random events. Most of our behavior is random: do we turn left or right? Heads or tails on a coin toss. Each choice leads to a different path for events to follow.

You can't go back in time, but if the whole process were to start again the chances of humans, evolving as we have, evolving the same same, forget it, there is not a chance of that happening. It is pure serendipity that we are here in our present from.

I don't see why not.
If you can't influence the world when you rewind, then whats the point.
