Darwin's attempt to find the origin of man was never about disproving the existence of God.
He grew up a devout member of the Church of England.As time passed his faith in Christianity dwindled,this can be narrowed down to 2 reasons.1) the
question of Evil,which has plagued many a man.and 2) the death of a daughter.
Though these things made him question his faith (and late in life he declared,
"I never gave up Christianity until I was forty years of
age."
he never denied the existence of God.In fact,at the time of writing On the Origin of Species he believed God was the First Cause.
In his book,The Descent of Man,he sees religion as being an important evolved human social characteristic.He says;
"There is no evidence that man
was aboriginally endowed with the ennobling belief in the existence of an Omnipotent God.On the contrary there is ample evidence,derived not from
hasty travellers,but from men who have long resided with savages,that numerous races have existed,and still exist,who have no idea of one or more
gods,and who have no words in their languages to express such an idea.The question is of course wholly distinct from that higher one,whether there
exists a Creator and Ruler of the universe;and this has been answered in the affirmative by some of the highest intellects that have ever
existed."
He also believed that a man can be an ardent Theist and an evolutionist at the same time,and in his lifetime he gave no support to those who used his
theory against religion.
So,if the creator of the evolution theory did not use it as a weapon against religion,is it right that others do so??
If he believed that evolution was real and a Creator existed too,is it not the duty of all Darwinists to share this information with people,less they
become like some ignorant religious believers who pick and choose parts of their faith??
In regard to the Bible origin story.
Just because God created all does that make evolution impossible??
Are we to believe that nothing changes over 1000s and 1000s of years??
(take into account how humans have changed)
Is it possible that the beginning of Genesis is just a story and God sowed the seeds of life and let nature take its course??
Is it possible stories/events have been mixed up and the Flood happened before Adam & Eve??
Imagine;God is angry at how life has gone,he floods the planet and starts again,but this time he creates rather than just sowing the seeds........
