AIDS between safe partners?

Is it possible for two people that don't have the AIDS virus, to get it after having unprotected sex?

Like, is it possible to /make/ it, without knowing it?
Or would you have to come in contact with a previous already existing form?

This is an easy question to answer and make you happy.
Two people without the HIV virus cannot make a nee HIV virus. Because it takes the body several weeks from the time of exposure or getting the virus until the test becomes positive, then two test-negative people could include one partner who has the hidden virus in the body and will later test positive and who could pass the virus on even when test-negative. Stay with one partner through 2 negative tests about 6 months apart and you'll both be safe, if you remain sexually faithful only to each other, and no other partners for now.

Only a person infected with HIV can transmit it. You cannot catch any STD from someone who is not infected.

Have you both been tested? It is possible to be born infected, as certain STDs can be passed from mother to baby. Always get a full sexual health check with a new partner before having unprotected sex.

Use birth control unless you are trying for a baby, too.

If you don't have it then you can't get the HIV virus. But one of you could be carrying it and could have given it to your partner. Also if you have had unprotected sex with someone who has it then you can give it to your partner and you could also having it without knowing it.
