Afterlife is a must

It is my great belief that afterlife is a must. There is no uncertainty about this very matter. Otherwise, life on earth, especially for human beings, is a kind of curse; not curse, more than that. Life was created, and each moment it is being created by the Creator. So, it is certain that the Creator is not so unmindful or imprudent that he should create lives for a specific period of time on earth & then the lives would die forever. That matter is quite impossible & baseless.
