IMHO, they are just things they cann't explain with their current personal knowledge ... and there is soooo much happening in the world right now that most people cann't explain, that I would say miracles are happening all the time and atheists cann't negate it. Insulting is the way their brains deal with it.
just because atheists don’t believe in the existence of God, and that he or she disagree with you on that (“that” as in your theism), doesn’t mean he or she have insulted you.
As to matter of “supernatural”, “magic”, “miracle”, or “myth”…
"Magic", they say.
They say "miracles", "supernatural", etc etc etc ... they even say "spaghettis" and in their minds is an insult. So they are.
What is really "miracle" or "magic" or "supernatural" in an atheist mind?
…none of that, are insults.
Plus, the NT, called everything that Jesus supposedly did in the gospels, as miracles; miracles that defy natural laws, such as walking on water, healing with touch or with words, stopping storm on command, etc, these miracles are supernatural, not natural.
Thats not insult. It is what it is, and miracles are no different from believing in magic, supernatural or the paranormal.
One of Jesus’ miracles was to turn water to wine for the wedding. We know today the chemical composition and properties of water, and the chemical composition and properties of wine, you cannot naturally turn water into wine, because wine required grapes, and it take some times to ferment grape juice into wine, and during that fermentation, thereby further changing the composition of juice into wine, as the wine have properties of certain level of alcohol. That’s not insult. That’s the fact.
Water alone, will never turn into wine. Another fact, not an insult.
How do you not see that it isn’t possible to turn water into wine?
To believe in such miracle, you would have to believe in magic transformation, because water is just water, and without fermentation of grape, there can be no wine. Again, not insult.
The question is, will you ignore how grape juice can naturally form into wine through the process of fermentation? Or will you still believe that this miracle can actually happen?
