Some counterpoints to Elledan:
1) There is no use for religion as an empty form without personal value to the individual. However, there is still Mystery and there is still Shame, which is the reality of memes that drives religion.
2) Perfection as an abstract is hard to imagine, much less practice. This is not what the Hebrew ethic means by "perfect" when it refers to growth oriented creatures. Perfect refers to the moral and ethical realm in biblical writngs, not to mathematical concepts. The human who attains "perfection" is the one who attains a level of observed benevolence from which there is no intrinsic possibility of falling away. That doesn't mean there would be no further ascendency.
3) There is a sense of oughtness which most humans bring into every situation. This sense of oughtness has much common ground amongst people of a wide diversity of ethnic and cultural backgrounds. Infact, to have a sense of conscious "oughtness" seems to be unique amongst the physical species we can observe. The loss of it is considered diseased and sociopathic. Furthermore, great thinkers in various cultures, but uniquely as a people amongst the ancient Hebrews, tied this sense of Oughtness to the same source of Shame and Mystery, and called them One.
4) In addition to "poetic myth" that teaches valuable lessons, the bible also includes many statements that, by genuine literary evidence, familiarity with obscure customs, archeological evidence, and linguistic style, bear the marks of eyewitness accounts. Furthermore, some of these eyewitness accounts, verified to have been written well before the events it foretells, accurately predict some events in amazing detail decades or even centuries before they happen. Based on this evidence, a genuine scientist , without mandating any particular religion, would consider the possibility that knowledge is available to us that cannot be confiremd by the five senses and that at times defies the typical limitations of space and time.
5) The chance that aliens (of similar or higher consciousness as humans) exist in the same space time continuum as us is something that can be chronicled and observed by science. Based on chronicled observations, it is apparently remote and beyond mathematical probability in the observable universe. The existence of a genuinely supernatural being that transcends observation is not a question that science can even legitimately seek to answer given its current paradigms. Such a comparison is not valid reasoning.
