text:  Yeah, it's a really good question. NASA defines it as a biosignature is life, but it's life, as you would know, as a simple form. As a matter of fact, you can walk out your backyard and there's all sorts of biosignatures out there. We call them insects. We call it, you know, whatever we see, plants. That's all bio. The fine line between bio and technical signatures is that a technosignature is more intelligent and has the ability to exceed its own environment or create something bigger and better.
