I think it's it's not if there is life out there, it's when...
For the time argument watch this, Wubbo Ockels say Time is a MAN-MADE phenomenon.

Quote from TED site,
Quote:
In his mind-bending TEDxAmsterdam talk, Ockels explains how ‘time’ is created by human beings, as a way our brains can make sense of gravity. The speed of light is constant, because it is made by us: it’s the clock by which we have calibrated our existence. Based on this premise, Ockels proposes a new way to explore life in our galaxy
