What's the sense of life?
Eschewing any religious explanation, which is usually more confusing that enlightening, there does not seem to be any reason or sense for humans to exist. When you start taking in the endlessness of space and the timelessness of the universe, we are mighty insignificant.
I believe we are just a quirk of matter and energy that evolved on the planet. We have no more reason to exist than our tiny star, the sun. Intelligence and self awareness is just a side effect of our physical level.
Keep in mind that if there is no end to space or time, so anything that can happen , will happen.
That said, I believe it best to live in harmonywith the earth and each other, enjoy our emotional, physical and mental capabilities and do as little harm to each other and our planet as we can. Because we are social creatures, we need to protect ourselves and our homes, care for our young and old and produce those neccessities for a good life.
We are neither dirt nor godlike. Just humans, here for a few years and than gone.

Why are we here?
We are here because, more than ten billion years ago, the universe borrowed energy from the vacuum to create vast amounts of matter and antimatter in nearly equal numbers. Most of it annihilated and filled the universe with photons. Less than one part per billion survived to form protons and neutrons, and then the hydrogen and helium that makes up most everything there is. Some of this hydrogen and helium collapsed to make the first generation of massive stars, which produced the first batch of heavy elements in their central nuclear fires. These stars exploded and enriched the interstellar clouds that would form the next generation of stars. Finally, about five billion years ago, one particular cloud in one partcular galaxy collapsed to form our Sun and its planetary system. Life arose on the third planet, based on the hydrogen, carbon, nitrogen, oxygen, and other elements found in the protostellar cloud. The development of life transformed Earth's atmosphere and allowed small furry mammals to take center stage. Primative men and women evolved and moved out of Africa to conquer the world with their new knowledge of tools, language, and agriculture. After raising food on the land, your ancestors, your parents, and then you consumed this food and breathed the air. Your own body is a collection of the atoms that were created billions of years earlier in the interior of stars, the fraction of a fraction of a percent of normal matter that escaped annihilation in the first microsecond of the universe. Your life and everything in the world around you is intimately tied to countless aspects of modern astrophysics.

Does God exist?
It is in need of pointing out that this question has been asked since the time of our first conscious awareness. Even though it varies in how it is asked, no other notion is anywhere near as universally represented in the thoughts of humans. When it comes to the question, “Does God Exist,” there are really only two possible conclusions: God either is, or He isn’t. There’s no half-way. There’s no sliding scale. Whether you’re an atheist or whether you’re a theist, there’s a certain level of knowledge, and there’s a certain level of faith. The glaring conclusion to this ubiquitous enquiry is definitive proof that the answer is not forthcoming by normal observation. If it were, then billions of humans would have no need of asking it. Many thousands of peoples and races have made up answers to satisfy our inherent need-to-know mentally. These answers vary to such a degree, that their only commonality is in the acceptance without evidence, of the existence of a supernatural realm.

Is there life after death?
Give me your telephone and I'll call you with the answer once I die :]
