Just adding my 2 cents worth to this interesting discussion. And it does seem more like a discussion, a sharing of different perspectives, than an argument.
Although raised as Christian, I don't practice or believe in any religion today. But I don't think that literal belief is the essence of religion, except among people who have a shallow, child-like, black and white view of life and the world.
I've learned to recognize that for many religious people, literalness is not important. The personal, emotional, psychological, social, and allegorical meanings they find in sacred stories - myths - is what's important to them. They need and want the structure and symbolism that a story-and-doctrine format of philosophy provides for them. Fine with me, so long as they're not encroaching on my disbelief, or promoting social lunacy (let them have their individual ones if it suits them) or killing in the name of faith and gods.

They did not think that Osiris or Tammuz or Zeus or Adonis operated on earth. This was the common view of religion until the christians came along and started this stuff about how it actually happened down here...
I think that what you - or the person you quote - are referring to is the historical literalness that exists in Judaism, Christianity, and Islam. Some other religions don't have that. To the Jews, and later Christians and Muslims, a god's actions become part of the literal, linear history of human beings. But, even in religions outside of those 3, there's a belief in gods intervening in real life affairs, which is the source of prayer, sacrifices, etc. - to influence god(s) in their favor. The Greco-Roman religions were more cyclical than historically literal, at least in the worship of dying and resurrecting gods. But, they, too, intermixed historical events with religion in their semi-historical, semi-religious epics, which were much earlier than the time attributed to Jesus.
The Greek and Roman gods,
did operate on earth, though. They had divine or semi-divine children by mortals. Zeus took the form of a swan to impregnate a mortal woman. The Christian god (Holy Spirit) takes the form of a dove to impregnate a mortal woman.
