BLOOD OF BABIES USED IN RITUALS

The problem with such miracles is that they tend to occur at the very moment that medical researchers and lab technicians happen not to be around. This aside, I see plenty of purportedly unexplained events online often, though not always, in the dim and distant past when standards were less, yes; though almost overwhelmingly reported from religious sources least disposed to be critical. This while the history of religious mendacity and the manufacture of relics is well documented. (It is worth remembering that the church has only verified a relative handful of such miracles out of the countless Catholic masses done over the last 2000 years). So why does this not happen more often, like every time a consecrated host is placed in water to dissolve? Is there some reason Jesus is playing hide-and-seek with the eucharist and only rarely giving proof of his presence in this way? More specifically to the central claim, in the case of blood (or bits of heart, etc) 'of Christ': I can't find the DNA in samples ever being sequenced to determine the ethnicity. Apparently the DNA of some samples have been compared and claimed to be 'the same'. However, even if that is true (and no one that I can discover has produced the actual test data to say that it is), that still doesn’t resolve to the target person who is presumed to be the source. It would be more convincing if the analysis at least proved male, middle-eastern genetic origin. I am also confused as to why, if the notion of transubstantiation means that the church holds that, in reality, bread and wine actually change into flesh and blood all the time, then it would be held a rare miracle if they actually do! Finally, let’s suppose you’re the one and true God, and you want to prove your existence. Do you play silly games with gobbets of goo, or do you show up in person and demonstrate your power and wisdom to anyone who’s interested?
