Aliens- Should we make contact or not?

I believe that we shouldn't make contact with aliens. It seems that we could cause more damage then good if we go out of our way to meet these non-earth creatures. Sure, it would be amazing if we could find that there truly is life on other planets. But, is it really worth the risk? Hawkings could be right; they might want to come in and just use all of our resources and leave us for dead. We don't NEED anything from these aliens, so why try to hard to meet/find them? It could only cause unnecessary trouble. There's always the flip side; the aliens could be extremely nice and fun creatures. They could actually help us in many ways. But, we don't NEED their help; we simply want it. Quite frankly, we don't even want their "help." We just want to find out who they are.
