This is entirely out of your hands.
One man cannot make a moon landing a success.
It requires a team.
People have walked on the moon before, sure, and it's made a lot of children want to follow in the footsteps of these brave heroic men but it's just not going to happen for you. Going to the moon just isn't interesting for government agencies anymore, and it's very very costly, and that money has to be spent on other things that are more relevant than your pithy dream of walking on a floating rock.
You better get over it now.
Also, making your parents understand. That is impossible.
