Of course science won't give us definitive proof of the beginnings of the universe. But it can tell us how we came into existence.

They are one and the same problem.
Behold the pseudoscientific claptrap of the atheist. Behold his philosophical and theological ignorance, his irrationality, his failure to grasp even the first principles or imperatives of realty.
Of course it can't tell us why we are here. Odds are, there is no why. In fact I would say if we can show the how, the why becomes a waste of time. Because on a long enough timeline anything that can happen will happen. There no longer needs to be a why.
Blah, blah, blah, blah, blah. Hysterical doggerel. Science answers one question, hundreds more arise. Science never gets anywhere near the
how either. Science can’t even affirm it’s own presupposition. You're deluded. We can't get beyond the singularity in terms of falsification. It's all mathematics and metaphysics from here on out. You atheists go on and on about how things are getting simpler and smaller relative to some arcane and imminent mastery unto the end of all the great mysteries, when in fact the more we learn, the bigger and more wonderfully complex and bizarre the cosmos gets.
The whole reason most people believe, those who have truly thought about it anyway, is that they do not think life can exist without god. That we are too complex.

There's something almost numinous about your superstition.

Science can tell us how life can come about.
No. It can't. That's pseudoscientific baloney! The religion, the superstition of atheism.

We are getting closer to that knowledge every day.
Biochemical engineering and abiogenesis are not the same thing!
Utter nonsense. The opposite is true. The more we learn, the more obvious it becomes that we will never be able to resolve the matter of life’s origin scientifically. Indeed, the more we learn, the more obvious it becomes that life did not arise spontaneously via natural processes. That's just your ignorance, your magical, superstitious atheism talking. You don’t grasp the matter at all. Only ignorant, atheistic laymen and depraved academicians talk like this. The pioneers and the leading lights of abiogeneic research know better. Miller, for example, disdained these kinds of hysterical claims and those who peddled them.

This is why so many in the religious community fear science. It has the potential to undermine religion, if not directly, certainly indirectly.
Oh shut up with that old canard. Christians don’t fear science. Hogwash. And there’s no God in the gaps. More hogwash. I'm light years ahead of you in science, I'd be quite willing to bet. Further, it is you atheists who disregard what abiogenetic research is clearly telling us about the origin of life, what quantum physics is clearly telling us about cosmological origins.
The new atheist: he’s that smarmy, obnoxious, smarter-than-thou fool who stupidity believes that science is the all to end all of knowledge, and yet he cannot see what science is screaming at him about God.
