They are clearly a sign that the whole concept of angels (and all other religious crap) is a product of human imagination.....
Agree with this part ^^
.... But apologists will always respond with the argument that all religious concepts were made such that we (or rather people many centuries ago) could relate to and understand. They will say, for example, that the concept of teleportation would not be understood if it was used instead. So it is pointless trying to argue with them over these things.
But not with this part ^^
I mean I don't think apologists have a case here. Or else, why all those stories about miracles, like parting the sea (Moses), walking on water (Jesus), flying on an effing flying donkey to the havens and back in one night (Mohamed). If we could grasp those, we could easily grasp Kent Clark style angels.
