How did we invent math?

This makes me very sad. I just don’t know how else to describe it.

Well we can't 100% assume this is true unless we see for ourselves, but it is more likely than not true considering the sheer numbers.

Anyway I'd say distance, interest and time are the factors.
>Distance
Put yourself in their shoes. If we could go anywhere in the universe, would we really care about what some non-space-faring race 5 billion light years away are doing? There must be far more interesting planets out there for resources, exotic life, geological study and leisure. You know, because you actually like being there. If you are walking along the beach with countless sand grains that individually are unique, but all look like the same shit to you at a glance, would you really care to stop and pick out a single grain? Is Earth that interesting? Maybe during the age of the dinosaurs they might have found this place pretty cool, and modern day earth might be a bit more interesting to them too due to us, however -

>Time
There have been many resets and tight bottlenecks in Earth's evolutionary history, throwing us back possibly billions of years behind in evolution compared to the luckiest worlds, meaning there are spacefaring races that were around millions or billions of years ago that are now gone. Epic beyond words adventures and conflicts have likely all already came and gone before Earth had even moved beyond unicellular life.

>Interest
Statistically, there are probably planets out there with say, huge deserts with dunes full of gold particles, that shimmer in the wind with splendor beyond anything we know. There are probably planets out there with forests reaching up for miles due to a low gravity/ultra-high density atmosphere environment, with biomes wild beyond anything we know. With the billions and billions and fucking BILLIONS of planets out there, that stuff is probably all out there somewhere, and so I'd figure alien races would be far more interested in trying to find those, than the myriad of salty mudballs like our own.

Bullshit numbers.
The earth is 510072000000m^2
Your aluminum reflector is 2500000000000000m^2

How can obvious stuff like modifying the perpendicular motions of waves go so unnoticed?
