Should we be trying to contact life on other planets?

I do not think we should be trying to contact life on other planets. I do not think so because i agree with Stephen Hawking. I believe that if we contact life on other plants then we will not like what we find because they are likely unfriendly and will use our planet. The life outside of Earth is probably more advanced than us. If we were ever to "invite" aliens we should learn more about them first and make the necessary precautions to ensure that if they are not friendly we can get rid of them. Like Stephen Hawking said life outside of Earth is probably not the E.T. aliens that we imagine them to be.
