Reply to comment by Independent-Cod3150 in Artemis is cool, but there really isn't a good reason we're going back to the Moon (or to Mars and beyond). by [deleted]
I've already pretty much talked it all out down below. Feel free to counter anything I've said there.
Edit(just saw your edit)
I agree that we shouldn't make any judgements about the number of civilizations based on our observational capabilities. But you can look to past history of life here on Earth and reach the same basic conclusions. Which I explored in more detail down below.

We have a very limited understanding of the first 3.5bn years of life on Earth. Nearly everything that can be studied is from the most recent 500 million years. There is insufficient data to extrapolate from.
It’s fun to speculate about the wider universe, but its all meaningless outside of fantasy. At the moment the question of life and civilizations beyond Earth is a black box that we’ve hung a mirror on.

Well if there is a great filter out there, it's probably worth thinking about for our own sake if nothing else.
