You have experiments that test a creator? Wow — publish now and you will be rich beyond your dreams.
>>Scientific methods can be used to prove that a form of intelligence created computers (if anyone needed such proof). If scientific methods can also be used to prove that a form of intelligence created the cell let them proceed in the name of science.<<
AI can be interrogated (via source analysis, etc.) As of this moment, no creator has stepped forward (in Christianity nor AI) to allow one on one corporeal interrogation, nor said how He (or it) will ensure than the supernatural processes can be used and repeated.
Trust me, there is no ID nor creation rule that fits in science.
Where did I say that?
