Antiparticles are all around all the time.
They are created in many natural processes
like radiation and fission in the sun.
We also make them in colliders,
like those at CERN and Fermilab.
These are antimatter. But if you wonder about complex
antimatter, for example, atoms made from antiparticles,
then that is very unstable but antihydrogen has been produced
at Fermilab. There is nothing, however, that tells us that
in regions of space separated from us that there could not
be entire antimatter galaxies and so on!

You cannot produce or store anti matter
Matter and anti matter were formed at the time of the big bang. They immediately reacted and destroyed an equal quantity of each. However there was a little excess matter which remained and formed the universe we have.

Anti Brain is made but I dont know of any anti Matter

Yes anti matter has been made but only in very tiny amounts and it only last for nano seconds before it anialates itself with some ordinary matter.
Try doing a search for CERN and you'll learn something.

Yes, antimatter has been made, but it is so unstable that it decays very very rapidly. I think only CERN and Fermilab have been able to make it since their colliders are the only ones taht can create enough energy. The SLAC and others are not big enough. The SSC would have been but the Clinton administration cut the funding for it.

Yes, antimatter has been around since the universe began, anti-matter explodes when in contact with matter so it can not be stored safetly. This is why the Universe is explanding because antimatter is getting destroyed because there is more matter.

Yes, since the 70's or 80's. CERN in Europe creates antiparticles continuously. Anti atoms have also been created.
Positrons are commonly used in medicine (TEM).

anti matter has been made but being as it's so hard to contain and so hard to make they haven't made any usable sized portion of the stuff yet.

I has been made, but only a few atoms worth for a fraction of a second - I read it in New Scientist a couple of years ago.

Anti-electrons (called positrons) have been made in small amounts. They actually have a medical use - they are used in PET scans.
