Our Earthly civilization is arguably 40,000 years old, give or take.
We haven't been around that long, compared to the rest of the universe.
Our technology has advanced to the point where many things that were unimaginable are now actually being made possible.
Now, if our young civilization could do this in 40,000 years, can you imagine what a million year old civilization could do? A billion year old civilization?
