Time and Space is so vast that alien civilizations may have already come and gone in that time span.
Humans have only been around for a blink of a eye in the timeline of the universe. It could be some alien civilizations are only starting to evolve from bacteria at this very moment, or another few have already gone extinct thousands of years ago.


















This is why urban sprawl (exasperated by car dependency) is killing our ability to get around independently.
Urban density is the solution and something people should support (even those that choose to live in rural areas).
With urban density comes better public transit, better public spaces, walkability, and shorter trips to work and shops.
One of my biggest fears with getting old is loosing my independence. Having to be driven everywhere, with no other viable option of independent mobility, would effectively make me a prisoner in my own home in a American style Suburban neighborhood.
