I'm completely on the fence about intelligent life being out there. The argument "The universe is huge, therefore statistically there must be intelligent life somewhere in it" is flawed imo. If we're going to talk statistics, we need a decent sample size before we can make any conclusions. If we looked at this solar system, we could say that one in 8/9 planets has intelligent life on it. If we looked at the X planets we have identified as uninhabited, we could say that 1 in X planets has intelligent life on it. Whatever we choose as our sample, we only have 1 planet with intelligent life, so we don't have a sample size big enough to make any conclusions. That's not to say there isn't intelligent life elsewhere in the universe, but to say that there must be because the universe is big doesn't make much sense to me.

Does that make sense?
