Einstein theories , specifically relativity, have been fascinating us for around 100 years yet with all the real and actual evidence of its validity we still consider it a "theory"..... How much more evidence do we need to make Einstein's theories into (or any theory really) confirmed facts and laws?

I'm new to this site and feel like my question might be misplaced. I'm sorry if it is and please correct me :)

Thx in advance!

See the question Laws and theories and the answers to it. The terms law and theory are somewhat vaguely defined so your question doesn't make sense.

Relativity, both special and general, is well enough tested that physicists regard it as an excellent working description of the universe. However it can only be an effective theory since it does not take into account quantum effects. We expect that its predictions will be wrong in regimes where quantum gravity becomes important.
