The Plausibility of Alien Life

[desertofwater]

Is it plausible that alien life could travel to Earth? Yes.

It is plausible that alien life would travel to Earth? No. There is nothing particularly distinctive about our 3rd rock from a rather ordinary star that would attract alien life here. About the only thing Earth has to distinguish itself from even the other planets in our solar system is our production of radio waves. Since this production has been ongoing for around 100 years or so, there's nothing to attract any alien civilization that's more than 100 light years away.

It is plausible that alien life has traveled to Earth? (I'm addressing this point only in the interests of thoroughness. I'm fairly confident that you don't ascribe to this idea.) There's not a single bit of verifiable evidence that it has and, given what I said in the immediately preceding paragraph, good reason not to believe it has.

Yeah I think if there really are Aliens out there they wouldn't come to earth unless they have some mad craven for a McDonald's
