I don't believe there is any actual meaning to life. The building blocks of Life started with the Big Bang, and ended up here, through the explosion of stars, the combining of atoms in certain patterns, evolution, natural selection, etc. Though, I will give in to the idea that we give life a personal meaning(subjective), though we can still have it as no meaning.
However, I will say, that a purpose of life is to experience. We, humans, are an extension of the Earth, which is therefore an extension of the Universe and Nature. We also have the ability of self-awareness. We are able to be aware of our experiences. We are humans, an extension of Nature, living in Nature(Nature and the Universe being one and the same). We are Nature experiencing Nature. We are Natures way of experiencing and discovering itself.
As a scientist once said "We are atoms learning about ourselves."
