I am a Christian i do not read bible.
Of course. If you read the bible properly you wouldn't be Christian.
All the holy books contain verses which are not compatible with the current cultural ethos. The bible is not an exception. Similar verses can be found in the Quran, the Bhagvat Geeta, and the Tripitaka.
Regarding the Bible, it's about time that people step up out of the quagmire of their stupidity, and start believing what it says, and then living what they learned to believe from it.

I fail to see the obvious benefits of people believing in flat young earth.

Me, too. However, the benefits would be a little better than believing in a flat old earth. Why? Because the young earth part is reality, if you can call 6200-y-o young.

Young Earth is a fairy tale.
http://www.nationalgeographic.com/travel/top-10/oldest-sites-world/There is no scientific proof for any age beyond about 4,500 years. There might be a lot of circular evidence, a lot of science theory, but there is no proof.
This means that, according to science fact, the earth is only about 4,500 years old. We can assume that it is older. But we don't know from science.
The Bible record might be a religious thing, but strong traditions among the Jews is the Biblical timeline of about 6,200 years, in their Old Testament, the Tanakh. They are a living race of people, not some dead race that cannot speak.
