I'm going to number my statements for quick reference (for myself and readers).
1 Word definitions were developed by a group of people.
2 A word often has more than one definition, and the user chooses the one s/he thinks is most appropriate.
3 Regarding any definition I use, we (writer and reader[s]) are a group of people determining whether the definition seems to be correct.
4 Two proposed definitions for the word 'god':
5 god - a higher-order being
6 god - a supreme being
7 supreme - superior
8 superior - greater in quantity/number
9 god (combo of lines 6-8) - a being that is greater in quantity/number
10 Among primates, man is a higher-order being than an ape.
11 Therefore, man is a 'god' in comparison to an ape.
12 Mankind as a whole is superior (greater in number) than an individual man.
13 Therefore, mankind is a 'god' in comparison to an individual man.
