Peace test01
The very verses you bring to support the death of Isa (AS) are the same verses that support that he is alive.
You are just being funny. Isa (as) being alive is not normal and can not be assumed by default. You actually need to positively prove that such an out of the extraordinary event actually took place. Reverse i.e. dying is normal and an every day experience so does not need prove. Numerous prophets or indeed people have no conclusive proof of dying but we do not take the belief that they are alive.
Where is your proof that Isa (as) is alive?
