Nope, that's merely argument from incredulity. You don't know how the universe came to be therefore an invisible magic man made it.<quoted text>
The working Universe as a whole support the idea of an underlying intelligence.
Not really, quantum fluctuations are scientifically observed. Radiometric decay is scientifically observed.Your idea that the Universe virtually popped out of nothing...thereby suggesting a effect without a cause,is quite ludicrous and is nothing more that a scientific fantasy.
Your invisible magic man also violates the same cause and effect "rule". Which potentially might not necessarily be a problem.
The only problem is that it's not scientifically observed.
