And humans do that and much more by squeezing opposable thumbs together ...

  I'd like to see you, or any randomly selected human, try to create a flying device by squeezing any parts of your anatomy together, like all spiders of certain species can do. Spiders are masters of tool construction and use, masters of manipulating their environment, and the only reason we don't recognise this more widely is because they don't do it in the exact same way that we do. i.e. they have the ability to produce materials to build tools with in their own body; which is, arguably, at least as good an idea as the idea of modifying materials obtained from the environment, as we do.
