Life is something possessed by many, many more organisms than mere humans. Some of those organisms are beneficial to human life, some are antithetical to it, and others simply peripheral. But it is all life.
It is my view, formed over a lifetime of thought (and based largely on the brilliant work of many, many people intellectually superior to me) that life arose naturally, though we don't know quite how, and diversified naturally, about which process we know a great deal indeed.
I don't believe many lives on earth would ask such a question as "what is the meaning of life?" Ferns certainly don't, nor microbes, nor ants and weevils. I strongly doubt that mice and squirrels are much concerned about life having any meaning. Their lives mean nothing more to them than eat and don't be eaten, procreate, and (though they don't foresee it) die.
Humans, and potentially a few other highly developed animals such as cetations, elephants, great apes and so on, might have some little glimmer of life being a bit more than that, and you can see this in how they care for their fellow creatures, and appear to really mourn their passing. But humans are by far the most aware of all the possibilities of life, and I think the only animals that can actually contemplate the question.
But I don't believe we will ever come up with a better answer than "whatever we choose to make of it." I do not believe there is some "being" external to humanity that has a purpose for human life, for the simple reason that there's absolutely zero evidence to suggest that there is. And for the record, the "visions" of highly imaginative human beings does not count as evidence -- for if it did, then ogres and gargoyles and fire-breathing dragons, pixies, fairies, Santa and the Invisible Pink Unicorn are all just as real, just as much the product of human imaginations.
Therefore, if you want a meaning for your life, it's up to you to devise one, and then do what it takes to give reality to that meaning.
