Where did the universe come from? Atheistic origin science has no answer.

[Sword of Christ]

Causally prior (not temporally) to 13.81 billion years ago, the universe existed in a tenseless state as a 4-dimensional (at least) 'block' of spacetime. This is what is known as the B-theory of time within the philosophy of time, which takes a static view on the nature of time and thus the past and future both exist. It has good support from the physics, specifically from quantum mechanics and Einstein's Special Relativity. Time 'began' with the inflation of the universe and this event we call the 'Big Bang. Whatever exactly it was that expanded isn't certain and may in fact be empirically unknowable due to the scale involved. I would cast my lot with the camp that views the conclusion of a singularity just being a mathematical object and actually showing flaws in the relevant theories, which we already know is the case. The problem is General Relativity breaks down at that scale, and we need a sound theory of quantum gravity to harmonize quantum mechanics with GR in order to have a shot at accurately describing whatever the heck it was.

So what made all these different physical dimensions and processes you're describing here and how did they form a universe precisely naturally balanced for life?

From there on, science seems to have a rather good picture, aside from abiogenesis, though its support has been frowing well, and it has some plausible accounts of it. I myself like Dr. Szostak's (not sure about that spelling) possible account of abiogenesis.

Of course life came from non-living material, even the Bible describes life as being akin to molded clay or dust from the Earth with a little of Gods spirit blown in.

Biological evolution is very well supported on all sorts of fronts. The theory of gradualism is very tight and well supported, and accounts for punctuated equilibrium from what I can tell, in addition to huge support from genetics and fossil evidence.

If it's part of the process in which life diversified and grew in increasing complexity over time, and it obviously did, then that's perfectly fine with the Biblical view of a purposefully made universe.

So atheists are actually very well supported I think.

Equally as well supported as theists if none of this would be evidence against God.
