Roswell Grey Alien Hand Problem (for me)

[ufopilot]

I've seen a sketch of the supposed grey alien hand on TV shows and web sites based on a nurse's sketching of the grey alien hand (from Roswell  crash, I think):



My problem is that I fail to see an opposable thumb of some sort.  I have learned that for us humans, having an opposable thumb enabled us to better physically manipulate objects - allowing us to evolve to a higher species and do a great many things.

How does an extraterrestrial being create ships and controls and whatnot (and be light years ahead of us in terms of technology) without an opposable thumb then?

Bueller? Anyone? Anyone? Bueller?

Okay. Here's another question I have. There appears to be some webbing between the fingers. This leads me to believe that the grey alien has at some point in its evolution been accustomed to a liquid environment. Is this the reason why so many UFOs are actually USOs? Have they been here all along?

I live in the Hudson Valley area of NY and am no stranger to unexplained sightings - going back to the 70s. I thought I could engage users in some meaningful conversation. I have questions and sightings but no answers. Looking at post dates and numbers of views it appears I am wrong in thinking there is anybody of substantial like mind out there on this site. Good night and God bless.
