I’m going to suggest if we could terraform Earth to be a sustainable, livable planet, that would be the best use of our technology, since we’re already here. It would also prove we could do it elsewhere. Why go to Mars, Venus the Moon or Mercury when you could figure out how to take all the toxins and poisons out of our own air here on Earth?
Think about it.
You know why we don’t? Because we can’t. It’s all a scam.
