What has mankind done to justify its existance?

Only Jehovah's Witnesses didn't follow Hitler into the trenches. They follow ( at the cost of their life) what Jesys taught:

(Matthew 26:51-52) . . .But, look! one of those with Jesus reached out his hand and drew his sword and struck the slave of the high priest and took off his ear. 52 Then Jesus said to him: “Return your sword to its place, for all those who take the sword will perish by the sword.

They are willing to die for one another:

(John 13:35) . . .By this all will know that YOU are my disciples, if YOU have love among yourselves.”

Hi,

You are absolutely correct. and have virtually answered your own question.God created man/ Gave him a brain and nouse to link us to him.(If we choose) Its is said god made us in his likeness God Like. When danger strikes we all make prayers to him. A long time ago I was A front line combat soldier It really is mind changing With another human being dying on the end of a bay nett Lots of very hard men change from none believers in time of stress

you are way too far an ego-maniac.

we exist because our parents had sex. no justification necessary.

stop being so full of yourself.

and pick up some garbage, for pete's sake, try and leave the planet a little better of for you being here.

The answer is because God so loves the world.

You need to have spelling lessons
