Are there not things one is rational to believe apart from scientific evidence?
1. Logical and Mathematical Truths
Science presupposes logical and mathematical truths.
2. Metaphysical Truths
e.g., The external world exists. The past is real. There are other minds other than my own.
3. Ethical Truths
One can't by science show that which is good--the Nazi war scientists were doing science just as much as those in Western democracies.
4. Aesthetic Truths
and, most ironic of all,
5. Science itself
You cannot, via science, prove that science is true, or use the scientific method to verify the scientific method. It's arguing in a circle.

With this, the thrust of your claim losses its power. So what if there are scientific arguments to life after death? Obviously, life after death would be something science cannot prove, and there are many things we believe apart from science.
