I would say whether you find an answer to your question depends entirely upon where you start from.
The naturalist philosophers here will provide a starting point that is a logical absurdity. That is, the universe owes its existence to nothing.
It is not my intention to state their case in a demeaning way, or to caricature-ize it. However, this is the gist of it--and its implications for ever finding a path to meaning in life are inescapable. There is none to be found.
Reason has been sacrifised on the alter of rebellion.
I thought it was interesting, the way you asked the question. "Why can energy transform itself into matter.."
If you keep asking why, and put the how out of your mind, you may get there someday. The why, and its resident implications for humanity, are infinitely more important than the how.
Why do we have gravity? Do we slap some cosmic-high-fives to one another, rejoicing at the good-fortune to inhabit a universe with such a law. Or, does it have some meaning, or purpose. A reasonable mind would consider the former, an absurdity, in my view.
Therefore, is it unreasonable to seek the meaning or purpose to human misery? Is it simply misfortune. Or, does it speak to an urgency in this life?
Why do we humans have this beguile-ing sense of spirituality? Do we heed brother Dawkins and sweep it under the Darwinian rug? Or, does it too, have a meaning and purpose?
Are all religions equally true? Or equally false? Is there only One Way?
Will the philosophers ever give us the truth? Or, can Truth be known, without first submitting oneself to It?
You exist for a reason, my freind.
