Roswell Slide

Alien photo released Tuesday in Mexico City by Jaime Maussan.
There are certain things about this photo that do move me to believe that this is an alien being.
I'm not 100% sure that this slide is from the Roswell crash, but I'm pretty sure this is an alien being.
What I think about the authenticity of this photo doesn't matter.
What does is the expert testimony of professionals.
