What is your evidence that there is no God?
It behoves those claiming that the Christian God exists to provide the evidence not those who don't believe.
Nevertheless there is so much damning evidence to prove that specifically the Christian concept of an all-loving all-powerful God does not exist it's worth mentioning.
Young innocent children dying of leukaemia - God is clearly powerless to prevent it or can but is totally indifferent to it, doesn't care
Young innocent children being sexually abused by Jimmy Savile and other predators - God is clearly powerless to prevent it or can but is totally indifferent to it, doesn't care. No loving parent would stand idly by whilst their own child was being sexually abused. Making excuses for a God that stands idly by is appalling by any standard. It's akin to making excuses for Hitler exterminating people in gas chambers saying, it's all ok Hitler had a grand plan for them. Utter delusion ignoring this.
Millions of people being killed horribly by a respiratory virus - God sits by idly, totally indifferent to the suffering. He has the power to prevent it but doesn't or else he's weak and can't prevent it.
Thousands of women forced into the sex trade whose lives are endless misery and suffering. God doesn't care or is powerless to prevent it.
Less the utterly puerile excuse of "free will" rears it's ugly and desperate head here's some more . . . .
Volcanos erupting and killing thousands of people
The recent earthquakes in Turkey and elsewhere killing lots of people
Tsunamis, hurricanes, tornados devastating homes and lives
Then we can move to the evidence of prayer and the Bible
The Bible clearly tells us:
John 14:13-1 - "Whatever you ask in My name, that will I do, so that the Father may be glorified in the Son. If you ask Me anything in My name, I will do it."
Matthew 21:22 - "And all things you ask in prayer, believing, you will receive.”
John 14:14 - "If you ask Me anything in My name, I will do it."
John 16:23-24 - "Truly, truly, I say to you, if you ask the Father for anything in My name, He will give it to you."
Billions of Christians over countless years have earnestly prayed for and pleaded for cancer to be eradicated from the planet as well as other diseases. Their prayers have never been answered. They did not get what they prayed for. The Bible verse is clearly false. This holds true for all manner of things people have prayed for in Jesus's name. The defacto apologetic excuse for this by Christians is that people didn't pray for the right things, didn't pray the right way. They will never face up to objective reality.
I could go on, but I know it's pointless here
The world is chock full of factual objective evidence that the Christian concept of an all-powerful all-loving God is pure fantasy and delusion.
As stated before this doesn't mean that "a god" of some kind does not exist, it simply means that if there is a god or gods then they are not all-powerful and all-loving. They are likely weak, or malevolent and uncaring.
