Some might say all of them.
There is no way to even make an estimate.
The ancient Greeks believed that gods have been around since the beginning of time, and also Greek gods don't exist, so Ares did not have a birthday.
Well by speaking gods are immortal they could of been since the beginning of time or later on but scientists think that they have been since the beginning. So about the Triassic Period if you don't know how long that is its 365 million years ago.
There have been gods since the first man walked the earth.
Since there has been gods and religions
Since after cavemen and before us.
more then you could possibly count, since the beginning of time man has come up with all sorts of Gods and Goddess to answer the questions we cannot.1. where do we come from?2. who created us?3. why are we here?4. what is our purpose?
hindus focus on different gods because they are fool .why as every one who has a little sense should think that if there are a lot of gods so the situation of the world in which we live must be destroyed .due to their disagreement .and there should be only one God to control every thing and in its proper way .and we see that since the world has been created no change has been occurred .that s why..thanks
Since the beginning of time, or Biblical time that is. The Hebrew God, has alsways been recognized as a male. I think this is part and partial the fact that in ancient times, the figure of power is more recognized as a male, rather than a female (sexism is not implied on purpose). At the beginning of the human race, the australopthecines worshipped short fat stones as goddesses and tall skinny stones as gods.
Since nobody has met the gods in real life, it has not been ppossible to measure them.
Hesiod's Theogony concerns the origins of the world (cosmogony) and of the gods (theogony), beginning with Gaia, Chaos and Eros, and shows a special interest in genealogy.
The Romans knew of very, very many gods from the beginning of their history to its endings.
In mythological since yes
