HCl and Water question

Why does Magnesium react with HCl and not water. Does HCl have a higher electronegativity than water? Thanks.

The chemical substance hydrochloric acid is the aqueous (water-based) solution of hydrogen chloride (HCl) gas. It is a strong acid, the major component of gastric acid and of wide industrial use. As a highly corrosive liquid.

Water isn't that corrosive, but I guess if you leave the magnesium in water a looooong time there will be some reaction

What is important here is that HCl in water is dissolved to H+ and Cl-, H+ is active reagent in this solution when it comes to Mg dissolving.

Magnesium does react with water. It reacts to form Mg(OH)2.
