Well, this is a very serious conversation so far. Might i inject a little levity into it? So much so, you just might start levitating after reading this.
I realize there are a lot of very predominant/strong left brainer types on this site..and so i realize that the below will not be popular. Never much been a fan of religion myself, and to some extent, when it comes to an ultimate creator being i'm more on the agnostic side since i've yet to have any concrete experience with "the" one.
However, i've had enough paradigm changing experiences to convince myself this much is true, that consciousness is fundamental/primary and that we are so much more than our physical bodies.
Since most of consciousness is not physical in the sense that we understand and perceive it to be, one is going to have a mighty hard time verifying that via physical based senses. Nope, got to deeper and more within. When you start to realize that nonphysical reality is real and moreover can be self verified through experiences that go far beyond chance, coincidences, or the like, then a whole new world opens up.
But is it really that important to know this? I'm not so sure it is for everyone. Maybe some. But ultimately, what's most important is the knowing of the importance of treating others and life in general, with kindness, respect, compassion and love. Sometimes specific beliefs can even get in the way of that.
Everything else is secondary to the livingness of that. But for those who are even just mildly interested in understanding Consciousness from a broader scope, i recommend a physicist named Tom Campbell who worked with NASA, but was also open minded enough to be aware that neither current science, society, nor himself had all the answers and so he experimented and tested extensively via self experience, the larger reality. Yes, he is a real scientist and despite his many "wacko" perceptions and experiences, is quite grounded and you can tell the guy is obviously very intelligent and perceptive.
He wrote a massive trilogy called, "My Big TOE". He was fortunate to have gotten recruited by well known businessman and author Robert A. Monroe, during his early days of lab experimentation. Bob said to Tom, "help me with the science side of this consciousness research, and i will help you with the direct, self experience side of it."
Well, the very skeptical, but just curious and open minded enough Tom might not have known what he was getting into, but boy did it ever lead to him changing so many of his very physically based beliefs and paradigms. There is nothing like repeated direct experience and physical world verifications to convince someone of something and change belief systems. Lack of experience doesn't really lead to true knowingness. Like Tom recommends, being skeptical but open minded and having experience is the most effective way to come to know truths.
A lot of men especially, i've noticed, pride themselves on being skeptical. However, i've noticed a lot of us aren't truly skeptical in the scientific sense, rather they outright reject that which doesn't conform to preconceived notions and so called "logic". That's not true skepticism, but belief system maintenance and defense. Women, as a whole and trend (but not all by any means), tend to be a bit wiser in the sense that they tend to be more in touch with their feeling, intuitive side which goes beyond left brain deduction and analyzing and that leads them often to being more open minded and flexible. In general, i find men could use more of that way of perceiving and evaluating info, and women could use more of some of what more men naturally do.
And so, thus spaketh the Justin, "become ye He/She's (or She/He's if you prefer) to know truth and wisdom, but i don't mean get a sex change job and all that."
Oh, and circumcision is in some health ways, especially for a primitive peoples with lack of modern hygiene convenience, very practical. Even with some modern advantages and convenience it can help a lot. I have a cousin who would get recurring infections until he was circumcised.
