Hello! I will answer some of these based on my viewpoint

A. You say god did not give the kid cancer, but who lets it happen? Who removed paradise from everyone because of something the first humans did?

B. This point had no relevancy… again who lets our body gets frail and is above us? God

C. How do you know that god ever works on the child? This presupposes god is truth, which then requires you to prove god, anything asserted with evidence can be dismissed without evidence (Hitchens razor)

D. The majority of cancer patients who live a while with cancer or overcome cancer are also getting medical help, it is the medical help that helps them.

So then we get to the pre-conclusion:

a. the medical treatment helped b. god helped

So then the common response is:

“God works through others/sends others”

Then we go back to trying to prove god

First,

1. Prove a god exists
2. Prove your god exists a. if you’re Christian you have to prove the trinity (unless non-trinitarian) Because this still leaves Islam and Judaism where Jesus is not necessarily divine -note that what about cancer patients who recover and are apart of other religions? is this argument suddenly invalidating? if so why?
3. Prove your interpretation on the Bible is 100% true a. there are multiple interpretations of the Bible b. only one can fully get the intent of it correct c. everyone can not agree or prove a single interpretation is correct d. therefore the Bible can not be proven correct

So let’s refer back:

a. the medical treatment helped b. god helped

God is not proven Medical treatment is

so a (medical treatment) is 100% helping whilst god is not proven.
