Agents of Shield's Biggest Plothole

 Hi Alex, 

To pass some time on a bored Saturday evening, I decided to write you a letter about an old, but good one. What IMHO is the biggest plot-hole in Marvel's Agents of Shield. During Season 5, the team is zapped forward in time to a post-apocalyptic Earth. 

In the year 2091, most of humanity has been wiped out by some unknown disaster, the Kree are running the place and the environmental conditions are nasty. 

In the end, the Kree are defeated and the remains of humanity are liberated. It is also revealed that the Earth was quaked apart a few days after the team left. Coulson and co travel back to what for them is the present, while the 2091 set about rebuilding Earth. 

Except, here comes the plot-hole....The 2091 folks are frakked on matter what. 

Why ? Well, let's begin with Coulson and co. Now that they know that the disaster is coming, the Shield folks set about preventing the disaster that wrecked Earth. And they succeed. Which means that the version of 2091 they visited now no longer exists. They've been erased for existence.  

But let's say they somehow escape that fate. Through some multiversal shenanigans, their timeline is still out there. And they manage to re-assemble the Earth using Kree technology and Inhuman/Mutant powers. There are two things that will still doom them...

1) The Earth shattered is the Mother-of-all extinction events. The bulk of Earth's flora and fauna are gone forever. But....

2) ...A key piece of Earth's ecosystem isn't ON it. It's in orbit of it. When the Earth was quaked, the planet's gravity field was also shattered. And without that gravity, there is nothing to keep the moon in orbit...

...which means that 2091 Earth is still doomed. Don't believe me ? Go to YouTube and ask what would happen if the Moon disappeared. Long version short, it's not good.

That's all I have.
