Probably depends entirely on who you ask. Most Christians (and other mainstream Abrahamic religions) will likely tell you that they are just myths. However there are groups of people who do still believe in the Greek Gods (and other pantheons for that matter) and honor/worship them.
Some real, and some conjured up. The Bible mentions the existence of the Sons of God roaming the earth "even giants from of old." this took place before the great flood a few millennia before even pyramids came to be.
it really depends. people believe what they believe, i think everything is ral, mainly because i just support other's belieffs, but i find it easier t believe these are real because "noonne is perfect" with most groups of gods they're seperated into different whatever's, but with the "lord almighty" "one true god" or whatever he goes by it's one thing. even if it is a god it's not entirely believable, see, it took Zeus 32 times on his own to make man, but needed help from a higher deity, it took god a bit of sand... heh, i'm so weird.
Maybe.Some people still believe in greek gods and goddesses.The name of this religion is called Hellenistic.But Some people call it greek mythology.Not that many people believe in Hellenistic anymore.Hellenistic is a old religion.I'm pretty that all the greek gods and goddesses are died because when a group of people pray to gods it makes gods live longer and powerful but when a group of people stop praying the gods lose there powers and die.But according to "Ancient Aliens" on the History Channel they are actually flesh and blood aliens, not "gods". So the greek gods and goddesses are aliens than that means all the gods and goddesses for other religions are aliens too.Think about it.I like Hellenistic it has a lot of gods and goddesses in it.Almost all the gods and goddesses in Hellenistic are relative.Like a BIG family.
