Hearsay, hearsay and more hearsay. There is no proof that the tissue has been in water, but the inspecting physician has been very adamant that tissue being stored in water for YEARS, regardless of distilled or not, cannot show the blood cells in the sample, because they would have been washed out ages ago. This leaves 4 possibilities:

• The people bringing in the sample were telling bullshit tales. This is by far the most probable reason.
• Someone who has reason to make it appear like a miracle has messed with the samples, replacing them. This doesn’t mean the people bringing the samples in don’t think this is authentic, but without a 100% secured chain of custody it cannot be ruled out. There are people who would be able to make a lot of money out of something like this, so this is the second-most probable reason, and would give the people bringing the sample in additional authenticity because they really believe.
• The physician made MULTIPLE errors while analyzing the sample. We can’t rule this out, but if he is somewhat competent, this is very improbable
• We see a miracle. As long as the chain of custody over the samples isn’t 100% watertight, as it is in this case, this isn’t even improbable, it is borderline impossible.

Bring us irrefutable proof (hint: you won’t be able to) that this sample hasn’t been messed with in the years before it landed on that physicians desk.
