Maybe that's what Jesus used on the people that he healed

In the whole Christian tradition, God/Jesus generally does not go for organ or limb regeneration. Two counter examples are a healed ear in Luke (but this may well have been resumption of hearing? details are a little light), and then a single Spanish example in the 1600s. For His own mysterious reasons, He simply doesn’t go in for that stuff, however much intercessionary prayer ends up in His inbox.

not an amputee, but he did heal a man with a withered or malformed hand in Matthew 12. he also healed plenty of cripples, so I don’t think it’s a stretch to think that some or many of them were missing limbs.

2 years I ago I sliced maybe 1.5mm frommy thumb-tip; when taking off the bandage, I could clearly see the "straight cut" and that some material was missing. Until today, it recovered completely

What, last night?

haha :D Sorry,English is not my native language! What I meant was: "During the last years until today"

Is this sentence better?

Lol, I once sharpened my knives and went to cook. During the prep I said, "wow I wonder how sharp the knife is", next thing you know, i cut about 1/4" of my finger tip off, right through the finger nail with zero resistance. Besides the blood getting everywhere and needing superglue to stop it, it grew back completely fine.

You shouldn't really sharpen kitchen knifes too sharp. And even if they're not super razor sharp (cutting a finger with no resistance), you should still warn people new to your kitchen or even family members/regular users right after each re-sharpening. Additionally, too low angle will make the knife very suspectible to blunting and/or require constant drawing on the sharpening steel¹. Unless you have super high qual…

> You shouldn't really sharpen kitchen knifes too sharp

There is a sentence among cooks: "only with a stub/butt knife you cut yourself" - isnt this true anymore?

I take from this that you don't, otherwise you would explain it

You're the one who believes magic is real, it's up to you to explain it. Extraordinary claims and such.

This is ironic. They didn’t say they believe. You offered your belief that you know something that happened long ago (extraordinary claim), and they are naturally curious how you could know that. If you’re a time traveler or whatever we’d be quite interested to hear more.

No I don't because I'm not claiming that I know that it happened

What can be asserted without evidence can be dismissed without evidence. There was no Jesus who performed miracles of healing

> What can be asserted without evidence can be dismissed without evidence

What’s your evidence for this claim?

Jesus, if he existed, didn't actually heal anyone or perform any miracles. That's mythology, not reality.

How do you know?

In your first comment, replace “until today” with “since then” and you’re good!

“Until today” is one of those English phrases that is particularly unfair on non-native speakers. You know “until” and you know “today” and so it’s completely natural to combine them in the way you did.

But as ever, English is dumb and annoying and hard work, all at the same time.

Retina is a good example of this. Zebrafish can regrow damaged retina, but while mammals have the same stem cells (Muller glia), they dont repair the retina, but form scar tissue. There is a lot of research and I think they have managed to modify rat genome, so that their retina has showns some repair abilities. The problem is that it often causes tumors. I have other retina permanently damaged, and suffer from doubl…

Ah, I was wondering the evolutionary reason why those genes would have gone dormant. Cancer is a sensible answer.

I think presumably Zebrafish aren't prone to retina cancer.
