It wouldn't.
Hercules is a mythological demi-god. This means that he has never existed as a real person.
Gods are not "alive" they are created by man for man, so they do not eat, sleep, have children, or die. If you believe in a particular god, then, it is alive for you.
I'm sorry to say this but God isn't alive. He may be alive in our hearts. But only in our hearts. Right now he's up in heaven watching over us.
Most religious beliefs suggest that God has always existed and is eternal, rather than having a beginning or end in terms of life and existence. God is often considered to be beyond the limitations of time and mortality, existing outside the confines of human understanding.
"My God, I'm old!"
Anything said about God must be based on His revelation of Himself to us. God is eternal. He has no beginning and no ending. God has always existed and will always continue to exist.
There is no way to tell; certainly Naqada in Egypt existed, so it is possible they believed/knew of Seth.
Assuming God exists and that God is eternal, yes.
God is with in us
Atheism is real and functioning, so in all respects one would certainly consider it alive. As there has never been any substantial evidence for any god, if the choices are 'alive' or 'dead' then one could consider God to be dead, if that is your choice.However with no evidence to provide God does not exist, then one can equally consider the opposite that God is very much alive.
I would do it on Poseidon, god of the sea and earthquakes.
