Aimless drawing of God in old comic (8)
I believe the answer is:
doodling
'aimless drawing' is the definition.
The definition and answer can be both to do with creating things as well as being present participle verbs.
Perhaps you can see an association between them that I don't see?
'god in old comic' is the wordplay.
'comic' is an anagram indicator.
'god'+'in'+'old'='godinold'
'godinold' is an anagram of 'DOODLING'.
'of' acts as a link.
Can you help me to learn more?
(Another definition for doodling that I've seen is " drawing idly".)
