Oh there is for sure so much more to discover. Like sure we've done a lot and seen nearly all but when it comes to depth and complexity that we've searched certain things it's actually very surface level. Think of how much more detail and depth we could explore certain places? There's probably so much facinating stuff just out of our vision, just below the surface or water or sediment of the bottom of the water, caves we haven't yet been able to explore. Then add the tedious Nature of modern day exploring, it really slows everything down or holds things back from happening at all. So my curiosity stays strong at how much more detail we can uncover.
