Mathmatics supports the formation of the universe from nothing.
Which 'god' out of thousands can be verified beyond the others?
Not a LOT of satisfying "mathematical verification" of the Big Bang.. Most of it is actually taken on faith...
Red shift, background cosmic radiation and Friedman's solutions to Einstein's ToGR. That's not enough?
All clues to where our little particles came from and where they are going and how fast they are going. But the ORIGIN and scope of that motion as theorized is a matter of faith more than math..
One should have good reason for having faith in something.
In science, often you accept "the best" explanation. And that often involves a little faith. Particularly in cases when the theory is completely beyond your ability to comprehend the magnitude or scope of the event or phenomena.
That's often "reason enough". When you say ALL of the material, energy, dark matter, and motion in the known Universe used to reside in a space that can barely hold an atom --- that's not simple, explorable or intuitive at all --- is it??
