Life in the Universe

I searched that this has not been posted before. These are 2 videos that speak about the possibility of life in the universe and why we have not found out yet. If in the 10 billion years of the Universe, have others sighted us?

The first part is about life being on Earth or everywhere in the Universe.

Yes, of course there is life else where in the universe. Proving it is an entirely different thing all together.
