What motivation does a crow have to build a jumbo jet? Furthermore, the vast majority of humans have no idea how to build a jumbo jet, and throughout the vast majority of human history, there were no jets - jumbo or otherwise - does this mean that we only have higher intelligence in today's world, now that we are able to build jumbo jets? For the vast majority of human history, we only had the simplest of tools and if we compared those humans to today, by your standards, these humans do not possess higher intelligence. However, evolution has not progressed nearly as quickly as our ability to work with tools has; as such, the human brain really hasn't changed all that much in even the last 10,000 or even 100,000 years! https://en.wikipedia.org/wiki/Evolution_of_human_intelligence#Homo_sapiens https://en.wikipedia.org/wiki/Evolution_of_human_intelligenc... Finally, you have no proof that crows would be incapable of building a jumbo jet, you've simply asserted that they couldn't. To be clear, I'm not arguing that they could, merely conceding that because they haven't done so, does not mean that they are incapable of doing so.
