It's not proof of the big bang, in fact, it's actually a problem.
Right, and if I say ...
It can't, scientists do and they do get it wrong and that's bad science e.g. evolution.
That's why science doesn't try to tell you what is.
The situation evolutionists face, not moi.
Everything you experience with your senses could be a trick ...
Insofar as scientific evidence is a thing that works at all, though, the big bang is pretty uncontroversial
Ha ha, you're the one that's assuming there's sufficient evidence. To evolutionists, the center of the earth is technically made of kittens, or at least, the thing that made the thing they believe is their "common ancestor".
and if the evidence doesn't seem sufficient to you in any practical sense, you should probably also be questioning lots of other things, like, for instance, "is the center of the earth actually made of kittens?"
