Antimatter and anti particles are same?can't we find some of them ?if particles and anti articles met,will...

....met will they destroy each other?
why are we made of matter other than the anti matter?
please answer all the questions if possible.
thanks you for your time.

They'll annihilate when they met each other and produce gamma rays. It's possible the Milky Way galaxy contains large clouds of anti-hydrogen

When matter and antimatter meet, they annihilate each other. They cease to exist, and energy is released. The only way they've been able to detect antimatter is by their electronic charges. Other than that, no.
About why we are made of matter rather than antimatter, it seems likely that only matter obeys the laws of physics. However, the same could be said if we were made from antimatter and we think in that perspective, that the laws of physics are random things floating around and doing random things.

your question is a play on words. antimatter has positive electrons and negative protons, and a normal matter who have the opposite of that thus cancellation occurs.
