If intelligent alien lifeforms exist, then why haven't we seen them yet? The universe has been around for billions of years and there are two trillion galaxies each with billions of stars. Shouldn't we have found something akin to a dyson sphere around a star or a galaxy yet??

We've only been looking for about 50 years, man....

It's a big universe, and assuming that everyone uses radio waves to communicate is a fallacy.

Because of the vast distance between our Solar System and theirs.
The universe is estimated to be only 13.7 billion years old. Assuming life throughout the universe evolved at the same rate life on Earth did, I strongly doubt any advanced civilizations even mastered interstellar space travel.
Otherwise, they would've found us by now within the boundaries of our little cluster of the Milky Way.

Astronomy has only viewed a tiny amount of the sky, and of that only a tiny spectrum.

We haven't even classified all the species on our own planet. What makes you think we should be able to see other fucking lifeforms from other galaxies

The reason you don't see star systems with life on them out there in the firmament is because, the eminently practical choice for a developing civilization when faced with the prospect of extravagantly wasteful solar bodies, is to shut them down and use all that sweet sweet reactive mass in their own reactors as needed.

Also gravity wells are a prison that render true spaceborne civilization an economic impossibility; therefore, deconstruct all planets in manageable chunks.
