Why Haven't We Had Contact From Aliens?

We have only existed for a micro second, have had technology to hear messages for a trillionth of that. We base our understanding of a "message" on our perceptions which would likely be utterly different to other sentience out there. It is beyond naivety to think "communication" would ever happen.

what if there's aliens

Take your tin foil hat off, ya big loon.

Shouldn't you be winning douchbag of the year on Imdb2 about now? 

If you believe that species like us become extinct around about when they get nuclear weapons and the population gets out of control, then yes, it is possible that we are the most advanced in the universe, as the window of time for others to be more advanced, maybe 200 years, is so tiny.

Indeed. In universal terms, the probability of an overlap in the times that two civilisations become advanced enough to develop interstellar space flight, to develop communications that can reach far away fast enough, to find each other in the vast emptiness in the first place, and to make that journey, all before they become extinct, is so unbelievably small as to make it hugely unlikely to happen.

I'm not so sure about that. We all think aliens would be hugely different to us, but would they? They would have to obey the laws of the universe, just like us. E.g. gravity, light etc. As for communications, there are only so many different waves in the universe, infra-red, UV, x, gamma etc. Wouldn't take too long to sync up.

And who's to say there aren't space aliens among us right now -  even those we might regard as human beings? Considering the size of the universe (or at least as far as we determine it to be) it seems almost a certainty that "intelligent life" exists elsewhere. If and when they decide to reveal themselves as such to us, then we find out for sure. For all we know extraterrestrial intelligence may be now pulling the strings of our very existence. This is certainly as likely as the divine forces and entities of religious belief being in the driver's seat - maybe even more so since it would be more consistent with the material universe as we understand it.
