Show us an example of something that has existed forever
There is a real definition of "outside of the universe." The definition lies in as many ways as you can say it. No there isn't. As far as science knows and observes, this is the only universe but there are a lot of hypothesis about multi verses. The term ''universe'' by definition means everything, saying ''outside the universe'' makes little to no sense.
I actually am a little surprised at you. Science attempts to extrapolate backwards millions of years, and then talk about it like it is reality. Science attempts to suggest that big bang is something that existed, but is unlike anything that we have today, even though it had the "seeds" of what the universe would become within it. But you don't even want to wrap your mind around the idea of outside-the-universe? How totally unscientific of you. Sounds like you are moving back to the limited scientific thinking from the 1800s.
