There is no evidence for the existence of God.

50. Well, it wasn't all that well thought-out.

You raised some of the questions that were clearly omitted from the basic setup.

Our universe isn't some simple little room with four walls and no windows or doors. Humans have only recently explored it, with the capabilities accelerating fantastically in the past half century or so.

Not only do we have doors and windows, we have the ability to create tools and processes to extend and analyze what we observe. We're not locked into some room. Instead, we have complete visibility of the entire universe, which is almost 14 billion years old and expansive enough to hold almost endless things to examine.

The analogy of that bare room is not at all representative of our complicated and still unexplored universe. The two things are not comparable. But, simple ideas suit simple ways of thinking, even if they are a poor match for the comparison. It reminds me of the simple examples that religious apologists use to distract from real explanations.

We know far more than the person in that featureless room.
