Why are we here?

What’s outside our universe? Is it possible for humans to ever know this? Can a video game character ever learn of what’s outside the game?
Why is there something or nothing? Scientists argue you can destroy energy, why was it there in the first place?

Either we are :-
1:a bad or forgotten school project of a type five godlike alien kid, having the knowledge to manipulate the universe as they please. [SIZE=1]we are not even type one[/SIZE]

Or,
2:no one has a clue why we are here so they make up stories about people creating us,apples,talking bush and donkeys,zombies…as we perambulate on

Others speculate about the mult-universe theory. If it’s true, we might never interact with them. The current universe is expanding but until when?

It’s all here on this earth.
Everything and anything that ever existed.

A very wild statement considering the universe is 13 billion years old and our earth is only 4 billion years old. There is a gap of about 9 billion years where life could have appeared and died.
