Please, Alien. Your planet should have agriculture.
Our planet have something calling climate cycle. We can’t really grow our favorite fruit if the day isn’t right. So we start to name something called month so according to our constellation in our sky or you can say the earth position around the sun. So we know when can we grow our favorite fruit. And be happy about it. It called calendar
So we have technology and we still adhere to this calendar so we know when do we do anything.
We are happy that earth circle around our sun. We love to party. So we use this excuse to party and be happy about it.
If you condescending alien find that we are not intelligent because we find an excuse to party then fuck you.
