I’m glad that you’re trying to understand! That’s awesome.
So, I don’t want to be rude, but your lack of knowledge is far too severe for me to correct in a post.
You are correct about spectrography being used in determining if there’s life on a planet, but there’s just so much that you don’t yet know.
If you haven’t seen it, watch the original Carl Sagan Cosmos.
When you’ve learned about that talk to me again. I’ll update you from there.
