Well, obviously they are both here, otherwise you would not be reading this.
To find out HOW it was created is as impossible to answer as what you would have if it WASN'T created.
The easy answer to that last one is "nothing", but think about that for a second.
If by nothing you mean a big empty space, no stars, no atoms, no nothing, but you still have the space.
If you didn't have the space, then what would you have?
Imagine something that isn't even a space and has nothing outside or inside of it. Could you? I can't.
Now go from that concept to the vast ocean of "something" that we know.
Look at your finger tip, the lines of your fingerprint, each is thousands of cells wide, each cell has millions of atoms that form the proteines of your DNA string, from which you were created 9 months before your birth.
Zoom out to your whole body, from there to the community where you live right now, country, world, solar system, galaxy...
Where does it all lead?
As unclear a question as where it all came from
