If anti-matter does exist, wouldn't it just blow us apart because doesn't matter like blow up or something when it comes in contact with antimatter?

Anti-matter does exist. It occurs in such small quantities however — never even in molecule* sized lumps — that there is no danger of noticing it, yet alone being blown up by it. When an electron comes into contact with a positron both are annihilated releasing a few gamma ray photons (in low energy collisions).

Yes, matter and antimatter annihilate each other when they come into contact.
Antimatter doesn't exist in any large quantities in the universe. It is, however, continuously produced in small amounts in the upper atmosphere, due largely to cosmic ray impacts. The antimatter, of course, doesn't live long.

Exactly.
That is why there IS NO anti-matter in existence near us at this time. Any anti-matter has been MAN MADE using Particle Accelerators, like the Hadron Collider in CERN Switzerland.
In these machine, anti-matter is made one or two particles (electrons and/or protons) at a time. Yes, they DO run into other matter, and annihilate themselves. and produce energy according to Einstein's equation E=MC2 (EE equals Em Cee Squared).
But a proton is so very very tiny (and an electron even smaller) that the energy given off when they annihilate is extremely tiny. Things become dangerous only when BILLIONS OF BILLIONS of anti-electrons and anti-protons get annihilated by "normal matter" particles.
It is thought (NOT proven) that at the Big Bang ,matter and anti-matter were created in ALMOST equal parts. There was like 50.0001 percent matter and 49.9999 percent anti-matter. The matter and anti-matter annihilated each other, leaving only that 0.0001% of matter unaffected. THAT is what makes up all the dust and planets and stars and galaxies we see today.
BUT -- which was MORE -- matter, or anti-matter. There is no way to tell! In fact, all matter in the universe MIGHT be anti-matter, and what we make in the colliders is really "matter"!
That boggles your mind.

Yes. That's why there's no naturally-occurring antimatter anywhere near the Earth.
