At the Big Bang antimatter would not have necessarily been separated far away from it's matter counterparts. Antimatter behaves physically identical to its matter counterpart. If we had a universe made entirely of antimatter the laws of physics would essentially be the same.

But what makes it an anti particle in the first place?

 

Antimatter is created all the time and is everywhere.

See proton + proton collision at 0.36c it'll produce pion 0, which is supposed to be made of up and anti-up, down and anti-down quarks,

or pion- and pion+ which are also supposed to be made of up, anti-down, and down and anti-up quarks.

 

We don't see antiprotons in our world, because they're quickly converted to photons as soon as they are colliding with regular protons in the atmosphere.

Astronauts do see it- when they close eyes they don't see black, instead little flashes.

There seems to be two things wrong with that: There aren't many protons to collide at high velocity in the vacuum of space, at least not within Earth's magnetic field, and second the photons produced by such an annihilation I'm pretty sure aren't in the visible spectrum.

What you're trying to talk about sounds like virtual pair annihilation which has to do with virtual particles and not anti matter.
