Is there a God? I don't know.
Who created the earth? I don't know.
Was creation of the universe just a convenient happenstance?
And also, what about life, human or otherwise; another accident?
Some claim life started from the collision of single cell organisms.
But, then, who put them there?
Do we really believe everything exists because of convenient accidents?
Rational minds know that an accident must have been caused.
Is this not true?
You decide.

In your decision processing follow your heart wherever it may lead
No matter what your decision God or not...
Life's golden rule should apply as Mathew said,
"So whatever you wish that others would do to you, do also to them."
If one lives by this advice he or she
is promised a peaceful life.
So the answer is not ascertaining who made us it really makes little difference.
What is important is the manner in which we
conduct ourselves and the belief we are all in this life together.
Whether or not one lives for God's sake or for the sake of the human race,
in the end, a good and worthy life would have been led.
