No, unless any evidence surfaces which demonstrates that there is an afterlife, I won't believe in one.
The classical mechanism by which one can supposedly live after death is a soul, a notion which, in my view, was disproven a long time ago, and is not taken seriously in neuroscience and psychology. The mind - essentially, everything we know and can do - is the product of the brain. If you damage one portion of the brain, the part of the mind which that part governs often ceases to be functional: if you damaged your hippocampus, it'd be extremely difficult to form long-term memories. And, when you damage the neocortex and other linguistic parts of the brain, your ability to communicate is severely impeded.
So, the concept that when our whole brain stops functioning, we can suddenly think again and remember our families and our experiences seems virtually impossible to me.
When we die, the atoms which make up our body will go back to the environment from which they came. They've been on a long journey - from the furnaces of stars, through space after a supernova event to, eventually, making us what and who we are. And, after that, they will be decomposed by some bacteria and make up a future ecosystem. The atoms may be eternal, but we're probably not.
