Yeah, we see no evidence that there's any form of life, let alone intelligent life, anywhere else. And I could say, well, we're not in touch with these other people. It is possible, but it seems, I mean, given the exponential impact of this type of technology, we would be spaced out based on over a large period of time. So some people that might be ahead of us could be ahead of us, certainly thousands of years, even millions of years. And so they'd be like, way ahead of us and they'd be doing galaxy wide engineering. How is it that we look out there and we don't see anybody doing galaxy wide engineering?
