I guess that depends on your POV: I’m pretty much a reductionist, so I find the various hypotheses re where the universe and life come from to be quite compelling.

There is no why, really.

The more interesting question revolves around should, from an ethical/moral perspective. The analytic tradition so favoured in the UK since Hume has been shown to be cracked (read, e.g., The Women Are Up To Something). Since WWII, progress has been made on that question, but Hume’s acolytes still cling dearly to mind, perhaps because of that same reductionism.
