There is life out there, with so many planets being found in their solar systems respective Goldilocks zones, it seems likely that many will be teeming with life - and a small percentage will have hosted (or currently host) intelligent life.

I think we will find life in our own solar system eventually, possibly on Ganymede or Europa.

If we are visited, there is a strong chance we would be like Neanderthal men in comparison to beings of superior intelligence.

Will humans travel to Mars? I think yes, maybe by 2030. Will humans travel beyond this solar system, not for centuries and we'll probably become extinct before we get anywhere near planning.

I think we could see human settlements elsewhere in the system - not in our lifetimes though.

I think we may find some radio waves from a civilization elsewhere, but we will be too far away from each other to make direct contact or to have a conversation.

I hope we can discover intelligent life forms elsewhere, it would challenge the fairy stories that have caused too many issues.
