Then why do Christians have to go around threatening their god will burn people for ever if they don't convert?
Christians do not have to do that - at all - neither necessary nor useful. Matters not to one who knows the difference between a supposed contemporary human threat and a Biblical truth.
Before you can call it a truth, you need to present sufficient evidence. Until then, it's just a Christian scare tactic.
There is no proof the sun will cast its light every day.
I never used the word proof, I used the word evidence.
We have plenty of evidence our sun is currently stable and will not go Red Giant for another 5 billion year.
How old did you decide the earth is?
You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.
You cannot over estimate the unimportance of nearly everything. John Maxwell
