im agnostic because i believe that one cant either prove or dissprove that a diety exsists or not because there is no real evidence.

Fair enough. From that position, you could also call yourself an atheist if you thought that the possibility of a deity existing was particularly small, even if there was no proof of no god (which would be close to impossible to come up with in any case). But if you feel that there being a god is just a likely as there not being a god, then calling yourself an agnostic is probably the best choice.
