    We’re not talking about planets hundreds of millions of light years. We’re taking about planets a few to hundreds of light years away.

    That is nothing. There’s been life on earth basically as soon as it cooled enough to not be a molten ball of rock. Like 3 billion years ago.

      Yeah but to see actual signs of life on those planets we’d need to either be able to see clear images of the surface, or have some way (other than the light method we use ATM) to detect microscopic lifeforms, right?

      I’m just asking to try understand better, the only mention I’ve heard of life on other planets have been from chemicals produced by life detected in the light that passes through the planets’ atmosphere, but I wouldn’t say that is definitive proof

        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.
