These morons know nothing.
They say the universe was smaller than an atom then exploded in the big bang and became larger than a galaxy in one trillionth trillionth of a second. they have no explanation why or how this big bang occurred.
They scientists also told us global warming was real. that has been proven a hoax . there is no warming.
If it happened once, it could happen again. Maybe it'll happen again in the next 5 minutes and we can take notes this time.
