We've known this for a while, it's old news...., it's moronic to think that there are over 100 billion galaxies, each containing about a trillion stars, and those stars all have a chance to harbor planets, and you think that not one of them has conditions ideal for life, life as we see it on earth is not the only type of life tht is possible, I'm sure there are beings out there that the human couldn't hope to possibly comprehend in any way, people that life has to be similar to us in order to exist, this closed mind set is usually what leads to the simple answer of we are alone, perhaps the first beings we come into contact with may not even see things the same way as us or even live in the same dimension, it's not impossible to Think that in the lifetime of the universe, a species evolved to exist perhaps in the time dimension and are able to travel through time the same way you travel around in the 3 spacial dimensions you exist in
