What is your best argument for god?

[jcm]

Any meaningful answer would be entirely dependent on knowing exactly what you mean by 'God'.. God is defined differently by different religions.. God, when defined by Man, is a poor attempt to describe what really is almost indescribable without resorting to our built in tendency to anthropomorphize.
Even those of the same religion can experience 'God' differently. Creator God, pantheic God, Tribal God... the 'God' inside us all...  impossible question to answer.

Regardless of whether you have voiced your description of god, you have already defined god and accepted that god is real. Beyond that, you will believe any religion that fits with what you have already determined god to be. This, however, has little to do with reality.

for someone/thing so unimaginable, how is it that you seem to know so much about "him/it"

These arent new or convincing for most people, they just happened to be what eventually changed ME into a theist.

1. origin-i can fathom no other rational explanation of the universe, beside a beginner.
2. abiogenesis-i can fathom no other rational explanation of life, beside a beginner.

There are several reasons. The frst and most obvious is to explain what could not be explained at that time. The second reason for the creation and appealing belief in God is psychological. Adults still feel a need for parent like qualities in their life. In religions such as Christianity, trasngressional appeals are also made that connect with the human conscience, thus affirming belief. Once they begin to experiment with having a relationship with God the illusion begins. They have an experience which they cannot deny, thus any future discoveries of logic fail to persuade.
