No, for a couple reasons. First, I have sufficient evidence to present my belief in a 'most likely format'. This does not mean that the onus is on me to present evidence in order to convince other people. So, you are making an assumption, there. Secondly, 'god of the gaps', is a silly concept. What gaps, etc., it has no place in a serious dialogue. Basically, merely because someone makes a thread concerning one topic, does not mean that they must prove the pre-suppositional argument, to others. That's impractical and the reason why we have separate topics, etc.
