Yeah, ruling anything out when we’re still finding new muscles (https://thehill.com/changing-america/well-being/medical-adva...) and weird structures (https://www.science.org/content/blog-post/what-s-obelisk-any...) in humans - to which we have plenty of access - seems deeply premature.

The traditional way to demonstrate this is how little we know about the ocean floor and the types, styles, and varieties of life therein.

Every time we look we find a textbook's worth of new types of creatures, and usually break at least one minor "rule" of how life works, for example, "dark oxygen".
