You are creating a false dichotomy for the poster based on the acceptance of a proposition "that every thing that begins to exist has caused." You are trying to start from a point that , perhaps you feel is self evident, on which we do not agree.
All I ask for is an example of something that has a beginning that is not caused and all I get is evasion and accusations. It's absurd. We can (possibly) have an infinite sequence of effects, but not an infinite hierarchy of causations. If that is not true, present some alternative scenario.
So please explain your concept of causality and how atheism entails such.
This is a case in point. There is no final explanation for causality, but the fact that things are the way they are has unavoidable consequences. Rather than deal with the real issues, atheists here just engage in a meaningless dance. "Either the living God is, or he is not. Either the ultimate Reality is alive, conscious and intelligent, or it is not. If it is, then it is what we call God. If it is not, it must be some form of blind process, law, energy or substance entirely devoid of any meaning save that which man himself gives to it."
Another rampant absurdity, at least among the atheists I've seen here, is that there is no understanding of the difference between contingent and non-contingent being.
Though I do find this little corner that
@viole has found you in amusing, I am not trying to discuss your assertion and its ramifications on your view, I.e. what the person gives up by arguing for first cause in the manner in which you have chosen to do.
Viole is a "dancer," one that has said some things that, if true, would force me reject virtually all the books I have written by physicists--the no increase of information, for example, or asking what ultimate reality is (if you have to as you cannot possibly understand), not to mention not knowing the difference between a philosophic assertion and a scientific one. There's just no credibility there. In many respects, I might as well be talking to outhouse.
