Question: why does life exist

This question is tremendous, and can be approached in so many different ways! We can approach it using physics, which would say life exists because the ideal conditions for life developed (like being the right distance from the sun, the right amount of water, etc.) We can approach it from chemistry, which is the right chemical reactions happened to allow for life. We can approach it from biology, which is to say evolution caused lifeforms of varying types to develop (but not why life itself started – still an open question in biology). A blend of these shows *how* life started, but not really “why”. We can approach it through religions – many of which say God made life!

As with many “why” questions, you are asking an impossibly huge question. I approach it scientifically, but still “why” is a bit out of scope of science, it is more interested in “how”. The true answer is “we don’t know”. We probably never will know “why”. All we know is that life does exist, and we can ask the “how” questions and answer them.
