Why god cannot heal amputees? Well... he did, once.

[smax]

With God, it's always wild speculation about what he did or what he can do.

With science, we see it with our own eyes and there is no doubt.

Science has done many of the types of things the bible claims but cannot substantiate. Science has:

Given the blind sight
Given the deaf hearing
Enabled the criple to walk
Replaced vital organs
Cured diseases

And the list goes on and on.

While religious people pray for a miracle, men of science put in the hard work necessary to produce one.
