all of the different religions just lend reason to the why; IMO they are both equally important to answering the most asked questions throughout History.
Highly appreciate this acknowledgment that religions (and philosophy) lend to the "why" while science lends to the how and what. Though "equally important" is not something I can go along with. I tend to value both, but one strikes me as concerned with the heart and mind, and the other is more interested in describing the clothes the emperor is wearing, what materials the clothes are made of, where those materials are derived from, and what elements make up those materials.
Science can give you the answers to how our existence started, how the universe grows, what happened billions of years ago etc.;
On all of these explanations, science would provide theories, not answers. Not (true) knowledge.
How the universe grows and what happened billions of years ago, strikes me as impractical. Feel free, anyone, to offer your understanding of why these particular matters (universes growth patterns and what happened 1 billion years ago) is relevant to human life in last 50 years, and/or today?
Our existence explained is, in my understanding, related to practical concerns. While not overly familiar with scientific explanation on this topic, I feel familiar enough to say science is explaining (or rather theorizing) what occurred, but not why. When a human process is involved (i.e. our existence) why and/or 'what is this for' type questions become much more important, than mundane paradigms that honestly aren't explaining all that much. More like changing the terms, reducing the building blocks, and rephrasing the understanding of what was already alleged.
if this does not lead you to question the existence of Divinity, you are the one not seeing the "whole picture", and you are the one disallowing yourself an understanding of how things were created;
Feel free, anyone, to provide here your best "how" things were created, and I'll take the opportunity to poke holes in the "why" that is likely to be lacking. Our scientific understandings of the nature of reality (really physical existence) can be fascinating, but is limited in seeing (whole picture) as well. In many ways, these limitations are 'built in' or set up via the basis for the paradigm. Such as... introspection is to be downplayed in favor of a psuedo sense of objectivity derived from consensual agreement of physical faculties. Downplayed is a nice way of putting it. Disregarded is more appropriate, and is basis of refusal to seeing whole picture, as if that is mark of 'objectivity.'
