I don’t know about the veracity of this claim, but to me, to assume we humans are the only life or even the most intelligent life within the vast universe is the height of arrogance.

An assumption as the the belief of something that is not contradicted by any fact whatsoever and does fit with all known data, is not arrogance. 8^)

Sounds like pretty clear thinking to me, while all else is whatchamacallit, oh yeah, - speculation.
