It is a bit difficult to talk about religion and science on a forum without pointing out opinions or even blaring flaws.

However, it is best to try to avoid pointing out the errors in an argument that is based on "faith."


Where a person stands today is not necessarily where they will stand tomorrow.
I have never seen a person change their mind on a big issue in a moment.
It is a slow and gradual process that happens through learning and increasing your understanding.

In regards to discussing any big issue:
Some will never change their minds and will reject any "information" that might give cause to them too. They simply don't want to.
Some will love to debate thinking it somehow builds their own righteousness.
Others will avoid the topic and prefer not to have confrontation.
A few will listen and honestly pursue the truth.

It is like that with most topics. But you can never change a persons mind. Only they can do that. They need to want to first and people rarely want to change their mind.
