Like almost everything in the UFO field, these claims aren't proven one way or the other, so you have to make up your own mind. My friends (a group of long time experts in this business) all generally dismiss the Peruvian summer claims. Why? Is this an intellectually honest opinion? Well, I agree with them. Here are the fragmentary reasons why:
1. Peru is an area of the world with a recent history of very bad UFO claims;
2. Such claims are especially poor when the native or aboriginal peoples get told things to believe;
3. Amazonian peoples quickly and naturally interpret odd things in cultural legendary contexts;
4. The first reports of this summer stuff talked of these floating invaders as monsters in cultural terms;
5. Only later did the idea that these attackers were "aliens" take over the narrative;
6. The area affected by these attacks is notorious for gang activity dealing with illegal gold dredging;
7. These illegal gangsters use low-level hover suits to propel them efficiently over jungle terrain;
8. The accompanying suits are helmeted and face-shielded and have jets at the feet;
9. One of the village elders was shown the picture of such a suit and said the alien looked like that.
Another of the elders did not believe that the suit explained it;
10. Subsequent actions concerning Peruvian claims pushed the Peruvian "alien mummy" idea again.
This alien claim has been thoroughly debunked as an embarrassing piece of BS; so this should have no connection with the claims.
As an aside, stuff like this (connecting native peoples' stories, art, legends to UFOs) occurs all the time. A couple of years ago some snake oil salesman was pushing an idea that a "rare and mysterious" form of sculpture had been excavated in Africa which pictured alien body form and "proof" of ancient invasion or instruction of mankind. This novel rare find was of course fascinating -------
especially since I owned one myself. Yep. That old native sculpture of mine (along with hundreds of others in collections worldwide) surely proved alien visitation. The truth of the Nomoli figurines is of course far different from alien invasion.
A picture of me and my friend Nomoli is attached. Now, how do I get a Peruvian Flying alien or even a mummy?
