The universe actually seems surprisingly young to me. If the universe is a mere 14 billion years old, then dinosaurs ruled the Earth for 1/50th of all time! And life has existed on Earth for 1/3rd of all time!
When I was a kid, I figured the Earth itself would be a blip on a universal timescale. It's kind of disappointing that geological and astronomical timescales are so similar.
Of course, it doesn't really change your point. If a billion years is a surprisingly short period of time, then 21 years is an instant.
