It is truly important to consider, and if possible, to know, what happens to us after we die. Some, who believe we are just accidental physical systems in an ultimately meaningless universe would have us believe that we have no existence after we die. Our personhood is finished as we become dead, rotting meat.
Two main theories are proposed in the modern world as alternatives to this view. One is reincarnation - the other is spiritual existence and eventual resurrection.
An interesting note: A great book to read on this subject is by Dr Maurice Rawlings, and is called "To Hell and Back". He is a heart surgeon who resuscitated a number of clinically dead people whose experiences were ... interesting. He discusses a lot of interesting things related to Near Death Experiences (NDEs) in that book.
We will leave aside for the moment the many reports of people being raised from the dead in Christ's name. I believe that this can and does happen, but you'd probably have to actually meet people who saw it or to whom it happened, as I have, before you would consider the possibility of such a thing. Let us go instead to the matter of Christ's resurrection.
The evidence for the physical resurrection of Christ is far more powerful than most people realise. The link above outlines just a few of the basic arguments that help us see this.
Christians claim that Jesus Christ not only died for our sins, but also rose physically from death as proof that God had truly accepted His sacrifice. According to the Christian teaching, we too will all rise from death one day. Some to everlasting life, and others to everlasting shame and contempt. (Daniel 12:2).
If there is good historical and testimonial of the resurrection of Christ, then we have powerful reasons for accepting it over the popular theories of reincarnation. It also provides evidence of the possibility that we too will rise from death at the end of the age.
My Views on Reincarnation and strong arguments against it
Reincarnation appeals to us because it offers another chance. It is often associated with the so-called "law of karma". That law basically teaches that what you experience in this life - whether good or evil - is a result of the good or bad deeds in a previous life.
There are many contradictory versions of reincarnation. Some say we come back as animals, or used to be animals. Others ignore that aspect of traditional Hindu teaching and lead people to believe we go from one human incarnation to the next. But there was a time when human beings, even life itself, did not exist on the planet! So where did we all come from then? And how does an animal or a micro-organism for that matter earn "good karma" so that it can come back as something more advanced in the "next life"? There are a lot of unanswered questions here. Perhaps someone well-versed in Hinduism can give me the teaching on some of these issues.
