Prove that murder is wrong without God. Heck prove good and evil are absolute categories of truth without God. If you look around I have spent a large amount of time explaining why God had sufficient moral justification for his actions.
Here is a satirical but extremely accurate poem on modern moral secularism. Pay attention to the bolded section please.
We believe in Marxfreudanddarwin
We believe everything is OK
as long as you dont hurt anyone
to the best of your definition of hurt,
and to the best of your knowledge.
We believe in sex before, during, and
after marriage.
We believe in the therapy of sin.
We believe that adultery is fun.
We believe that sodomys OK.
We believe that taboos are taboo.
We believe that everythings getting better
despite evidence to the contrary.
The evidence must be investigated
And you can prove anything with evidence.
We believe theres something in horoscopes
UFOs and bent spoons.
Jesus was a good man just like Buddha,
Mohammed, and ourselves.
He was a good moral teacher though we think
His good morals were bad.
We believe that all religions are basically the same-
at least the one that we read was.
They all believe in love and goodness.
They only differ on matters of creation,
sin, heaven, hell, God, and salvation.
We believe that after death comes the Nothing
Because when you ask the dead what happens
they say nothing.
If death is not the end, if the dead have lied, then its
compulsory heaven for all
excepting perhaps
Hitler, Stalin, and Genghis Kahn
We believe in Masters and Johnson
Whats selected is average.
Whats average is normal.
Whats normal is good.
We believe in total disarmament.
We believe there are direct links between warfare and
bloodshed.
Americans should beat their guns into tractors .
And the Russians would be sure to follow.
We believe that man is essentially good.
Its only his behavior that lets him down.
This is the fault of society.
Society is the fault of conditions.
Conditions are the fault of society.
We believe that each man must find the truth that
is right for him.
Reality will adapt accordingly.
The universe will readjust.
History will alter.
We believe that there is no absolute truth
excepting the truth
that there is no absolute truth.
We believe in the rejection of creeds,
And the flowering of individual thought.
If chance be
the Father of all flesh,
disaster is his rainbow in the sky
and when you hear
State of Emergency!
Sniper Kills Ten!
Troops on Rampage!
Whites go Looting!
Bomb Blasts School!
It is but the sound of man
worshipping his maker.

That actually proves my point. What a strange conclusion.
Buddha was no more capable of assigning humans worth or making murder a moral crime than you are. However that does not mean his morals are not good just not justifiable without God.
