This thread is a bit difficult to parse, indeed.
Its title is
Science can only discover what G-d has already created/evolved in nature?
And that is more of a premise than a question.
If there is a God that created existence itself, who might possibly know whether he chose to make existence "complete" or instead as some sort of germen that would later develop on ways that he would not necessarily know in advance? We can only speculate, guess.
Then again perhaps a creator God would see fit to hide part of what is real from science for some reason. Or for that matter, maybe from religion as well. Who would know?
As for the request in the opening post, I don't think I understood it very well. Taken literally, it is a request for a complete list of statements "on behalf of science", with qualified and categorized sources.
But what is a statement on behalf of science? Science is a tool, not an employer or master.
It is difficult to give adequate answer to a request that I understand so little of.
