“Infinity or eternity must exist. If it didn’t, then everything must have proceeded from nothing at the earliest point. And if nothing was the earliest point, then there would be nothing now. Thus, infinity/eternity is proven by the very fact that there is something.”
This is a quote from a writing called Fatheism. This writing explores the only options that we have on the table as to what caused the universe. It looks at each option and proves which option is the correct one.
