When I was lil, the "how and why" books, I think thats what they were called, showed the moon breaking off from the earth. Then we got to see man landing on the moon.
Now i can look at an object in the sky, look it up on stellar or similar then find images taken from earth, hubble, spritzer etc. So much change in so little time.
Being a believer in life existing somewhere other than earth, I always have a glance upwards, you never know what you might see. I reckon "they"know we are here and are sending signals, we just dont have the right receiver yet. I also think that they dont want a bar of us due to our behaviour as a species. Ive seen things that are unexplained, I want to see more, thats why I look.
I have an inquiring mind, partly formed through those how and why books that I never believed anyway.
