Lol the earth has maybe a billion years at best to support complex life without us. Then the Sun heats up and makes our climate change look like a joke

We are the dominant species of the planet, and the best hope for a continuation of earth biodiversity when the planet is no longer habitable.

Especially if the noob is a parent with their child... People with telescopes love letting kids look through their telescope (as long as they are old enough not to move anything).
