Womb to the Tomb to the Womb

The last thing I want to be is a pessimist, in the same regard that this class isn't teaching us about atheism, but I had a thought. Life is an experience, and it's span is an experience from the womb to the tomb, however well cataloged and remembered, right? Starting from conception to coffin is another way of putting it. But the thought is what if it was the opposite? What if life itself is a tomb, even though technically death has nothing to do with it because that's why they call us living beings? Death is inexperienceable and separate entity of existence. Although, by living aren't we technically dying? Thus if life is synonymous with tomb then what would be the womb? Simply, the womb would be the things we came from before life, that experience separate from life, and out of nothing we came into existence and from existence we'll get back out and leave it eventually. And, well then, I suppose that would make the womb the earth, mother nature, or whatever other title you can come up with. The womb is dust because from dust we came and to dust we'll return. The point is, dust is us and therefore so is everything else. Walt Whitman became a bridge and put his experience as that bridge on paper. That's one of the purpose of poetry, literature, writing, and education in general; to become something more, something you've never been before. Consider this suggestion, sometime today please talk to an inanimate object because, even though the thing can't talk and write like you and I, they can hear. They share the same soul as you and we have to share the same world as them.
With that, here's something else to consider:
Lucretius, from what I've gathered, believes that the soul does not persist through the decomposition of a body. A body's lifetime is equal to the soul's. In that context the soul is limited as opposed to, and correct me if I'm wrong, Ovid's belief [stunningly similar to Buddhism] that the soul is immortal, transformable, and can essentially be reincarnated. In that respect, doesn't it seem that Ovid' beliefs are considerably more optimistic than those of Lucretius? Then again, how can we prove that a tree has a conscience?
Given the challenge above I'd say that I'm more Ovidian than Lucretian.
