All of these feelings are then, fleeting?
Nope, they are the things that last.
Are these wonderful feelings that you have described limited to the life we live on earth? Will they someday not be with us?
No one living will ever know.
These fundemental questions form the roots to why I know that there is an afterlife.
It may be why you
believe there is an afterlife, but you cannot know it.
I have begun to think that the other species were created for us.
Not only is that a very egotistical point of view, it makes GOD out to be an absolutely cruel unthinking bastard. Do you mean the billions and billions of critters that have existed were created just for your enjoyment? How sad and pitiful. How can you devalue life that much?
For us, there is an afterlife, a loving creator, and destiny.
While that might be a nice thing to believe, the reasons you've given so far have been pathetic.
