I find it highly unlikely that we could ever find a species similar to our own – we developed under very specific circumstances and the likelihood of that very same process being replicated elsewhere has to be close to nil.  Could there be intelligent life under another form? Of course. We have it on this planet, too. Are we likely to be able to know of it or communicate with it?  No idea.  I’m going to lean toward No.  Could there be intelligent life that utilises technology similar to our own?  No idea.  Again, we evolved under specific circumstances and I don’t think there is much hope that what evolved with us – our technology – could be replicated, either. 

But who knows?  Perhaps our universe is much like described in that ST:TNG episode where all bipedal life forms evolved from one primary species that ‘seeded’ various worlds with their DNA.  

Or perhaps there is a ‘god’ and it has created all sorts of variations of ‘humankind’ or other intelligent species elsewhere and it’s just a matter of time before we collide with them.  

Whatever the case, I hope our own species can evolve a little further intelligence before we start interacting with others (the film Arrival gave an interesting depiction of what this might look like).
