A fined tuned argument.....Heywood style.

[tor]

What a nice, sensible, rational debate! I like this Heywood. He reminds me of someone...

OK, here's my issue from logic, rather than cosmology.

You offered 4 options. Fair shout, you included some viable ones.

However your argument seems to be what we in medicine call a diagnosis of exclusion. That if it's not B C or D then it must be A.

But this does not follow, because it assumes that there is no E. It ignores the vastly likely possibility that there is stuff we don't know!

Imagine you are a norseman, a thousand years ago, applying this logic to lightning. You'd settle on A (thor) because you could not justify B or C (whatever they might be).

Doesn't work .

Nice you're making progress!
