That's got the potential to be a very very long answer. Yes, there are some of us out here. I'm Pagan, and have been for most of my life. I am an animist, ie I believe that 'God' is the life force that creates and destroys, and that everything has a piece of that spirit within; that in this way all life is interconnected and all eventually ends up back at the source, like a raindrop will eventually reach the sea to start all over again. To further express this, all life is equal (with no heavenly godhead in charge - every life fragment being as equal and important as the next.
Many (most?) Pagans believe in personified Gods/Goddesses, and these are usually the nature Gods of the country or area you live in or are descended from. So, for instance, here in Ireland most Pagans are either Wiccans (Witches) or Druids, and worship nature through the Celtic (or for some, the Norse) pantheon. In England, the Saxon or Celtic Gods are revered, and so on. Almost all Pagans believe in the sacred duality of nature, hence the belief in the absolute equality of God and Goddess.
We try to attune ourselves to nature and the cycles of the planet, and try live in a mostly positive frame of mind.
Most, but not all, Pagans believe in reincarnation, but there are those who believe we go straight to a heaven-like world called 'Summerland'.
For the most part, we celebrate the 8 sabbats of the year as they mark the year's cycle. They are the solstices (summer & winter), the equinoxes (spring and autumn), Samhain (Halloween,,, start of winter), Imbolg (at the start of spring), Bealtaine (Mayday), and Lughnasadh (at the start of Autumn). In addition, the moon's cycle may be marked by worship circles at the full and new moons.
