My brother made a good point

[Zidneya]

He said that while scientists try to disprove God, science changes everyday, what's right one day is wrong the next, so how can you rely on it? Meanwhile God and Christianity is never changing.
He also said he was speaking to a former evolutionary scientist who said there's no evidence for evolution, to be fair though I didn't hear much of that story.

Science doesn't care to disapprove God. Science cares to improve our knowledge, technology and solving our problems. It just happen that all those things tend to disapprove God by themselves. You make it sound like every scientists wake up in the morning saying: "I'm gonna disapprove God".
God and Christianity ain't never changing? Tell that to all those religious persecutions and discriminations we had in the past.
Also I would like to know the name of that evolutionary scientists along with your definition of good point.
