Picture the board game “Life” (I think that was the one...)
Imagine you have no money. You can get from the bank a $20 and a $20 Promissary Note.
No wealth was “created,” yet you have money and anti-money.
Similarly, could there not have been spontaneous creation of matter and anti-matter?
Nope because the matter has to exist. You cannot create matter out of nothing, unless of course you have super powers that don’t seem to exist anywhere that I have looked. The same is true of life on the planet earth, no science has been able to explain how it started, it has become so embarrassing to them that they(scientists)are now reduced to the theory that life came here from outer space on an asteroid or some other interplanetary vehicle, thinking this would shut people up but totally ignoring the fact that this does not explain how life started else where in order to be transported to earth. Nope, you can create matter from no matter, period.
