Go look at Drake's equation. It is admittedly just an estimate, but reading all the factors will help you get a feel for why we haven't been contacted by ET yet.

You don't know that there is no life on other planets. The universe is huge and we have yet to explore even 10% of it. Some people believe that the universe is never ending. There could be dozens of planets out there that harbor life--humans just don't have fast enough vehicles to reach them. It takes years to even get to Mars and that is the closest plant to us. Maybe you should get some books and try to read up on this.

Have you been to every other planet in the "know (sic) universe" to be able to make this statement with such confidence? Or, are you interpreting Genesis as implying this, thereby making your argument entirely circular? All *I* really know is that they haven't come to my house saying, "Take me to your leader". Excuse me, someone's knocking on my door.

Who's to say it didn't. And if it did, it may not have evolved as it did on earth. It would have evolved based on the environment of the planet.

It has, but unlike humans the odds of anything like us are too high.
