Delta G of formation of water is -237 kJ/mol, so why doesn't H2 and O2 form water in room temperature?

It has to do with the kenetics of the reaction. Lavelle said in lecture the first day of kenetics the example of the diamonds turning to graphite. The reaction has a negative Gibbs Free energy, but it never occurs in real life.
H2 and O2 to H2O is a similar case.

Thank you! Been struggling with this all month!
