Here Foolestroupe this should help.
We do not know if there is any other intelligent life in the Universe. Of cause it is not impossible, but we have no way of knowing how likely or unlikely life is.
By definition any Universe must contain at least one intelligent species and we cannot tell whether we are alone or not, until some evidence is found.
Sighting the vast size of the universe as proof is an action of faith not evidence.
If the evolution of intelligent life were ubiquitous then we would expect there to be evidence flooding in to are telescopes, there isn't.
Therefore intelligent life must be much rarer and farther away than commonly believed.
The idea that Organisms from distant stars let alone another Galaxy could travel to Earth in spacecrafts is ridicules.
