Have you saw God today or have you seen God today?

In the past tense you would say "I have seen God today", because that is something you 'have' done. You could also say "I saw God today". This makes sense due to the lack of the Word 'have'. In most other languages there is only one way of using the past tense, in English there are three. 'I did see God today', 'I have seen God today', and 'I saw God today'.
