Affiliate Marketing Secrets

Someday we will make contact with a sentient species from another planet or galaxy, I am completely positive about that. What I was wondering is, if our species are gonna be in contact with each other constantly then it will be quite obvious that at some point we will try breeding with each other. How would all major religions deal with this (i.e Islam, Catholicism, Buddhism, Hinduism)? Would they be ok with it? Or would they call it bestiality?
I posted this here because I wanted to know what you guys think. If you are not affiliated with any religion that’s okay, just try to answer with an open mind.
