Testing on animals vs Humans? SHOULDN'T EVEN BE A QUESTION!

About a month ago in my government class we had discussion over if its ethical to test on animals. Basically my teacher, the lovely Ms. Pinkwasser, separated the class into two sections. Test on Humans or test on Animals. I believe that it shouldn't even be a discussion. With all due respect to animals and people who believe that we should do tests and experiments on humans over animals, you really do need to reevaluate yourself. Now some people may get on my case and bad side over this but please have hardcore evidence as to why we shouldn't test on animals over humans. Some people might say "oh wow Luis you're an animal hater" but no, you just have to think more logically. If the tests are safe then sure why not, but if there are chances of bodily harm, there shouldn't be a debate about it.  Ask yourself, what do lab rats provide for us besides testing.... Ill wait. Like my great friend Jeremy said, "Even if scientists were to test on prisoners, it would more than likely be considered a direct violation from the Eighth Amendment". So even if people try to get a movement going to push out animal testing, goodluck. I know I sound harsh and i apologize but come on people, lets be smart here. (apologies for the late blog post)
