However, in all fairness, do you really think an eleven year old in 1947 America, after gazing briefly upon a pile of debris, has the technical knowledge to be an authority to ”recognize its unique properties” and to judge whether it be of “human manufacture”?
Good question. All I can say is that the mind of an eleven year old is like a sponge soaking up all kind of data especially when it is confronted with something this unique. All I could do is compare the debis with familiar material, and decide that this is not like anything I had seen before or since. Thanks for the question.
The conventional explanation is the strange lettering on the debris was manufactured in a toy factory!

For me the strongest argument against the Roswell alien craft claims is that none of the eyewitnesses seem to have taken the trouble to document their observations back in 1947. So far as I know, we have no diaries or affidavits prepared at the same time as the supposedly shocking events. We have apparently sincere documents prepared 40 or 50 years later. These are obviously subject to the games that memory plays on all of us. However, I am sufficiently intrigued to read a couple of books on this subject, and then I will make up my mind.
