Creationism is apologetics. The implications for Genesis being mythology are historic, seismic. That renders Calvary meaningless, because there was no Adam and Eve, no Fall, no inherited sin nature to be redeemed from before an absolutist God. Hence the Christian life is puerile. Christianity is really the Jesus cult. Thank you, Saul of Tarsus.
God is redundant, superfluous.
I don't have a faith.
Another atheist who is an expert on something that does not exist according to them and who makes sweeping claims that are totally unprovable.
So, as for Genesis being mythology, you have no proof.
Saying calvary was meaningless is devoid of reality as you do not believe Jesus existed so you can't say that something does not exist and then say it is meaningless because if it does not exist, it cannot be anything.
You do not know there was no Adam and Eve and if there is no inherited sin nature, where did sin come from?
As for christianity being puerile, you have chosen to ignore the fact that there are many brilliant men and women with minds that are able to compute the most difficult of problems that have embraced christianity.
In addition christianity is the Jesus cult as the original church was a branch of Judaism that was known as "The Way" with Jesus as their Messiah and which became the most successful of all belief systems in terms of followers.
As for God being redundant. You wish. Today all over the world christianity is growing at a phenomenal rate.
And finally as for you don't have faith all I can say is "man, know yourself." Everyone has faith in something, even if it is nothing in the case of atheists. Without a faith in something you cannot have a worldview because a worldview is an expression of what we believe in and what you believe requires faith.
It is very clear from your suppositions that you are enunciating what you want things to be not what things are. That to put it mildly is a fool's paradise.
You need to think more about what you say instead of just trotting out cliches that prove nothing; are nothing; ignore logic and contain very little intelligent conversation.
