I viewed your link and randomly selected 4-5 of the "contradictions" and basic knowledge of the bible and historicity dispelled them. I'm not going to go through all 50. Sorry you get out what you put in lol. But I've heard many of them before and highly recommend the "Whole Counsel of God" podcast which walks through scripture verse by verse and addresses the most common Catholic, Protestant and Post-Modern critiques of scriptural "contradictions" which are typically due to bad theology, poor historicity, translation errors, cultural ignorance etc etc It's also a great way to learn scripture in a deeper way.
If God exist why bad thing happen
This is a meme in Christian apologetic circles because non-Christians always think it's a big own when it is really just a demonstration of a lack of understanding of what Christianity is actually about -- Redemption. The story of how the world enters a fallen state is explained in Genesis. The fact that the world is fallen is critical to Christian theology and the process of sanctification.
God does not play by your rules. The struggles we face on Earth (often of our own creation) are for our salvation. This is what the bible and church tradition teaches.
I have a more expanded response in this thread here for some other points -- https://lemmy.ml/post/30390799/18750134
