Everything was lifeless nothing was moving.
There was no time, no space. Just something not even the size of a pea. This something all by itself started to expand at some point and is still expanding.
I want you to go get in your car put the key in the ignition. Do not turn the key. Do not press a remote start button. I want you to sit in that car until it starts by itself.
This is exactly what you and everyone else is telling me happened with that smaller than a pea thingamajig the universe came from.
No-one has told you that.
Why, then, are you claiming that everyone has told you that?
