A comment by sparkling about "carving away" the excess inspired me to outline the cases given in the statements. Please keep in mind that by the symbol --> I only mean that one thing leads to another, and I do NOT mean to use it as a material implication. Also keep in mind that I only covered the points that I personally took as being part of an argument or relevant to an argument. So "my opponent must do X" -type comments are entirely omitted.
Anyway, here they are:
Michael's OP(1) When nothing happens, nothing happens
(2) Can't traverse an infinity
(3) (2) --> universe began to exist
(4) (1) and (3) --->universe has a cause.
(5) scientists agree with (4)
(6) unconscious mechanisms cannot self-initiate --> the cause is conscious
(7) if it's arbitrary for the cause to be conscious then it's also arbitrary for the cause to be unconscious (

not sure about this one)
(

conscious creator of the universe --> theism
(9) polytheism is a arbitrary --> (Abrahamic) monotheism
(10) Muhammad ate mushrooms --> Christianity or Judaism
(11) status of Jesus deciding factor
(12) fourth gospel --> Jesus claimed to be God/messiah
(13) Jesus claimed to be God/messiah --> Lewis trilemma
(14) empty tomb was public & guarded
(15) culture didn't believe in bodily resurrection but reported sightings
(16) witnesses to resurrection became martyrs
(17) NT transmitted faithfully
(18) all the above --> Christianity probably true
Sparkling's OP(1) scientists doubt god's existence
(2) Biblical stories appear invented
(3) Biblical authors are unknown
(4) hand-copying and unqualified scribes --> text transmission untrustworthy
(5) we do not know the origin of the universe
(6) scientists suggest universe may not have a beginning
(7) scientists suggest time has no meaning apart from the universe
(

(7) --> "beginning of the universe" is meaningless
(9) scientists suggest branes collisions caused the universe
(10) up to this point is sufficient to rebut arguments
(11) argument begs the question
(12) assumption that conscious creator is interested in life is unwarranted
(13) only considered three out of thousands of possible gods
(14) WLC thinks trilemma is unsound
(15) Jesus could have been mistaken (

about his divinity?)
(16) his followers could have deified him
(17) common for myths to develop --> (16) more likely
(18) modern text of Bible has inconsistencies and mistranslations
So there you have it.
