1 ~ The ontological argument offers no evidence of any kind, and its logic is effectively obfuscation; deity existing as an idea does not necessitate its reality outside of the mind.
2 ~ The first cause argument is, in a nutshell, a simple argument from ignorance. It also makes the assumption that there must
be a 'first cause', which, if you ask any physicist, when it comes to the early universe, quantum mechanics, etc., is far from axiomatic. Also, it makes the absurdist, argument from ignorance-style assumption that any 'first cause' which exists cannot have had any cause which caused
it, effectively resulting in the self-destruction of the argument; in other words, if a 'god' is posited as a 'first cause', one is presumed not to ask what caused that 'god' to be there. There are two solutions: an infinite regress of gods creating gods creating gods, which ultimately defeats the argument; the realization that the 'first cause' could be literally
anything (a magic catfish, a quantum fluctuation, Dr. Manhattan... take your pick), and thus that it is entirely possible that it could have been a
natural cause, rather than a supernatural one. Given nothing
supernatural has ever been demonstrated to exist, the default probability indicates that a natural explanation is almost certainly the correct explanation.
3 ~ As an evolutionary biologist by vocation, the argument from design is one of my pet peeves, for certain... I am unaware of any single example of this allegation which is not explained infinitely better by natural principles than by supernatural propositions. Natural selection can produce organisms which
appear designed, for sure, but the evidence overwhelmingly supports an entirely mechanistic, evolutionary process as the explanation for these alleged 'designs'.
4 ~ The moral argument, like the design argument, is blissfully ignorant of very basic natural principles; in both cases, evolutionary science is one of the primary fields called. The moral argument presumes that morality is something which must have originated with a mind, when, in fact, it is much more elegantly explained by emotion, and by basic social dynamics (i.e., tribes that don't murder their own members tend to last longer; people don't like having their possessions stolen, therefore it would be hypocritical of them to steal from others). There is no universally-accepted ethical principle which is not present and acted by non-human species, and which can very easily have arisen sheerly out of the process of natural selection.
Really, it's the fact that you seem to consider those to be the best arguments for the existence of god[s] that makes people like me realize that
there is no convincing evidence or reasoning behind the claims of theism.

Try to realize it's all within yourself / No-one else can make you change / And to see you're really only very small / And life flows on within you and without you. / We were talking about the love that's gone so cold and the people / Who gain the world and lose their soul / They don't know they can't see are you one of them? / When you've seen beyond yourself then you may find peace of mind / Is waiting there / And the time will come / when you see we're all one and life flows on within you and without you. ~ George Harrison
