Einstein’s general theory of relativity suggests that our universe is finite but lacking a boundary or outer edge. Huh ? No comment..lol

In this context, "lacking a boundary" does not mean an infinite extension into the past. I believe Einstein was specifically talking about a "hard stop" at the "Big Bang" with the disclaimer that stop is where our human understanding begins (or ends). It doesn't mean activity wasn't still taking place. In fact, the Bible suggests it was. It's tough to get the human mind around.
