That depends....on what the questions are? Suppose God himself came and planted himself right in the middle of a science conference. At that point, he could be observed to a certain extent, and scientists could then observe different aspects of God and form testable hypotheses concerning the nature of the many facets of God. Existence of any entity, any known reality envites inquiry...”why is this here, how did that come to be”. Yet God hasn’t chosen just yet to come to a scientific conference (though Christians do argue that God came as Man and dwelt among us for a period of time). Until he does, God is a forbidden question to science, or “to the greeks foolishness”as Paul would have argued.
God calls himself “I am that I am”, he is the “IS God” who puts the “IS” in everything that exists, indeed backstops all of matter and keeps it from flying all apart. It is said that men are made in the IMAGE OF GOD, or “I AM THAT I AM”. There-fore all humans who have uttered the phrase “I am” in a conversation proclaim witness to the author of that Image; we cannot help ourselves. Imagine then the poor atheist stuck with having to use the phrase “I AM”, not knowing that when he uses that phrase, he bears witness to the very God he would deny as non-existent!
“Suppose God himself came and planted himself right in the middle of a science conference.”
Meeting someone is not a matter of science. But if it’s generally believed that God has been somewhere recently, a true scientist would be curious about the magetic field in the room, the oxygen level, the temperature, etc.
