Do you have something to base this belief on or is it just your opinion?
Howdy, ICANT!
I can field this one: at about age 4 yrs we develope a sense of other our own reality and the reality of other beings as 'intential beings'.
That is to say before this age we see other people as 'not like us'. People are counted as not being self aware and thinking exactly the way we do with no individual identity. If we know something, 'they' know it too.
This is called 'theory of mind'.
If we do have souls I would contend it starts here.
