The fossil record for cephalopods is actually pretty strong because most of them millions of years ago belonged to families that had hard shells, like the nautilus of today. They're some of the cheapest fossils you can get your hands on due to how common they are. They ruled the seas for a very long time as the most abundant form of complex life in their habitat.
Close relatives of modern squid and octopus which took over after the fall of the hard shelled families are much less common since in many, the only thing to fossilize is the beak (though some like cuttlefish have hard "inner" shells). That being said I'm pretty sure we do have ancient beaks that scale to creatures that would have been larger than even the colossal/giant squids of today.
I know you don't have much respect for them but everything I've just summarized would be extremely surface level for a real evolutionary biologist. The evolution of cephalopods is interesting considering their physiology differs so much from ours, but I don't assign credit to aliens for their existence any more than I would a snail or slug.
I put much more stock in your knowledge of the ocean than folks with a biology degree bud. Not only do you spend a lot of time on the water, youre obviously intelligent and have studied this stuff as well apparently. I dont believe in the way we date fossils though...baked into their calculations of isotope decay etc are assumptions that the environment on Earth over time was the same or even similar to what conditions are today...which we have no idea if that is true and i think its almost certainly wrong. Climate alarmists do the same regarding levels of gases in the atmosphere etc...lots of assumptions in the calculations which we have no records of. In fact recorded history and therefore what we know as science is such a brief blink of an eye when compared to the proposed age of the universe around us that i think its foolish to put much stock in any of our current understanding of the world around us... that doesnt mean we should ever stop learning and measuring, trying to understand what is around us. In fact i believe we should as much as possible...it just means I have very little faith in what some folks (and books/articles) state as facts. We just dont know as much about this planet or universe as some people like to pretend we do. Thats my opinion anyway...
