Everyone has a bias based on how their life has formed their worldview. That's the point of presuppositional apologetics. People cannot evaluate anything outside of their worldview unless they recognize it. Most don't.
Yes, everyone is biased, and mine is indicated by the following statements:
The second type of answer is that life is NOT a farce—that existence has meaning, and how one believes and behaves does matter for some non-arbitrary reason (the UMI/God, cf. Rom. 1:20). This answer seems more appealing and almost logically imperative, although some people appear to prefer the paths of nihilism and KOTH (cf. Matt. 13:14-15).
A person who believes cosmaterialism, moral nihilism and that life’s struggles are meaningless frequently tends to seek escape even via suicide, whether by one act or by a downward spiral of self-destructive behavior. Until/unless this option were somehow proven beyond doubt, moralism or viewing life as meaningful seems to be the better belief.
The adherents of naturalism posit that humans instinctively accept the validity of morality or of acting in accordance with a reciprocity principle or the “golden rule” (do unto others as you would have them do unto you, cf. Matt. 7:12), and they are satisfied with whatever meaning can be derived from this earthly existence. The problem with this view is that humanity has also had a proclivity toward evil throughout history, so there is no basis for saying the negative force toward others is not equally valid and for mandating a universal golden rule or moral imperative. Logically, all it can offer is a “pyrite suggestion”. Morally, it merely continues KOTH (“might makes right”).
The atheist opinion indicates that the existence of a supernatural Deity is not proven, although it is not disproved either, which means that the evidence needs to be evaluated honestly. Atheists assert that one cannot prove a negative, so the burden is on theists to prove God exists. However, this assertion assumes God is not the positive “I AM” (see axiomatic belief #1). A neutral statement about ultimate reality is the following: “It is logical to remain open to believing all credible possibilities (those which present sufficient evidence) and to hope the most desirable rational possibility is true.”
