Our whole universe was in a hot, dense state, then nearly 14 billion years ago expansion started. Wait...
The earth began to cool, the autotrophs began to drool
Neanderthals developed tools
We built a wall (we built the pyramids!)
Math, science, history,
Unraveling the mystery
It all started with a Big Bang!
Is there any other coherent ideas about appearance of the universe?
I havent heard one. This argument so wide that a whole discipline has deen devoted to it.
I mean philosophy..................
