I am simply responding to your assertion that world before Christianity was a dog eat dog uncivilized wasteland and Jesus taught it morally.

On the contrary, before the advent of Christianity Greek and Romans had dialogs on various topics. IFAIK Science and Philosophy came to a stand still for a thousand years till renaissance happened. If you evidence to the contrary, please do share some references.

Bible divided the world in believers and heathen so claiming it promoted universal brotherhood is laughable. World was never a perfect place, Christianity made it worse.

this was a dialog about whether Greek philosophers said the same things, but better. The rest is your own invention.
