If atheist Chinese scientists in 2013 can come up with valid, peer-reviewed scientific papers today, then science isn’t dependent on Christianity.
The entirety of the original post is mere trumpet-blowing. You might as well argue that without the fire making skills of the pagan caveman, modern science would not have been possible.
You confuse the creation or invention of something with its use.
Of course many people can use a tool which they would have been incapable of inventing, prevented as they were, as in this case of the ancient Chinese and other non-Christians, by notions that were of obstacle to that development.
The concept of laws of nature is the tool in this case, which the Chinese couldn’t grasp, let alone create. Once the concept exists and is widely used, even they can employ it.
Your irrelevant example of fire-making skills reveals that your knowledge and understanding of what is science is very limited.
