I agree with you 95%!
However, there is the planet seeding theory some people believe where extra-terrestrials purposely planted their genetic material on planets that could be hospitable to life. That would suggest that aliens could have similar traits with different evolutionary characeristics.
Of course, that is not science. I wouldn't write off the idea as impossible though as I could see humans trying to do the exact same thing.
I am about 99.9999999% sure that aliens DO NOT visit the Earth. Don't get me wrong, I would be willing to bet that there is life on other planets, I just have my doubts that the types of travel needed are possible, or that it is likely a planet with life on it just so happens to have intelligent life on it at the same point in time of us and is close enough to travel to. When you consider how old the universe is and how species on Earth anyway (our only example) only exist for a fleeting moment, the number of things that would have to be just right for aliens to visit us makes it seem almost impossible.
