Charbrah,
Thank you for asking your question so well. This is one of the questions that has been haunting me as well, and the replies in this thread have been very helpful.
You mentioned science explaining life, but science cannot explain why *anything at all is existence. *Try looking up information on the search for Higg’s Boson, (aka the “God Particle”). The current, most accepted theory in particle physics, the Standard Model, needs this particle and its corresponding field in order to explain why *any particle has mass, and what holds them all together. * Without it, according to the widely accepted Standard Model, all particles would fly apart at the speed of light. Scientists have been searching for this particle for years, and have not found it. So, recently they recalculated the mass of the theoretical particle, and are continuing the search. Also, there’s String Theory, that goes another level deeper than the particles of the Standard Theory, and says that everything is made of massless strings, like rubber bands, and that theory requires the existence of several additional spacial dimensions… It all makes me smile.
Thank you again for your questions and all of the thoughtful replies.
