Just look how far and advanced technology has exponentially grown in just the past 100 years.
Indeed, or an advanced civilization capable of sending powerful radio/light signals out could have died out billions of years ago. Or conversely a billion years from now. The amount of power and size to radiate a signal out to our Galaxy is unfathomable let alone a moving target like Earth is quite imaginary.
We were taught stuff like this in 5th grade back in the 60’s, yet today’s schools today are more concerned with putting men and trannies in girl’s bathrooms, shower, and sports calling them the opposite sex. Sad.
