You don't care about getting a reasonable explanation, you care about getting an explanation of everything, right or not. That's why you're not seeing this on the same level as we are.
No, I'm basing it off of arguments you people use against Religion. "If god exists, show us proof."
If the Big Bang happened, show me proof, not a couple of links to concepts that have been known to change every century because the process of our understanding keeps growing.
Show me proof beyond a shadow of a doubt that this actually happened, fossil records, video evidence, anything other than "Oh we just assume this is what happened because things seem to point to this but really it could mean anything."
I'm playing it on your level. A reasonable explanation isn't based on theory. Would you fly blindly into a black hole because theory says that it can take you to the future? Are you prone to believe the theory that the light barrier is unbreakable even thought we've proven we can break the sound barrier? Or will we keep trying simply because we will eventually find a way to do just that? Science as we know it is not 100% in any case on such a grand scale. I'm asking you from a scientific standpoint, not as a bible thumper. Where would we be if people did not question science and make us think and reevaluate what we know? Isn't that the very definition of scientific progress?
EDIT: So quit using religion as an argumentative crutch. It's a weak attack against something you don't care about to try and justify your own pitiful self worth. It's the same as saying "You're stupid because you're black."
