Actually, this is a Christian discussion forum. People are allowed to make statements about basic Christian doctrine like “God created the world” as if they are fact. It’s the debated stuff that we argue about, like whether God created the world 6,000 years ago or whether he used the evolutionary process. From the official discussion guidelines:
“Also, since this is a Christian discussion forum, we expect that basic Christian presuppositions like “God is good” and “the Bible is true” will not be constantly challenged by those who do not share those presuppositions. People of all beliefs are welcome to discuss evolutionary creationism here, but this is not the right place for debates on God’s existence or the general merits of the Christian faith.” FAQ/Guidelines
