This is fascinating and honestly, a little mind-bending. The idea that there are about 8,000 more advanced civilizations in our dimension, but we can't detect most of them... it makes you think about how much we still don't know.

The part about not needing an atmosphere really stood out to me. We assume life needs what we need air, water, certain temperatures. But if most civilizations don't even need a planet's atmosphere, then we've been looking for the wrong things all along.

Here in Ghana, we have stories passed down about spirits and other worlds. Reading this makes me wonder if those stories came from somewhere deeper.

Thank you for sharing this. It opens the mind.
