Well... We don't have enough manpower or materials to build enough spaceships for everyone's safety. We can assume a select million people (Prolly the rich and famous) will be on the spaceships watching the spectacle, or running in the opposite direction. Now, assuming we have the technology to accomplish such a feat, it would take quite a while for a object as big as Earth to achieve enough velocity to get it moving. During this time, the people left behind on the Earth (Hopefully not suicidal) would be doing everything in their power to stop such a spectacle. If they succeed, they would still be a lot farther from the sun, temperatures drop considerately, most water animals and tropical animals are wiped out, and we wear many layers of clothing just to get to school. Eventually we can fix it and put us back, and if the million who escaped and condemned us return, they would most likely get executed in front of the angry masses.
Humans fail to stop the earth hurtling into space towards Mars, meteor impacts become much more common and much deadlier, temperatures get colder, and we probably left the moon behind a few weeks back. When the time comes, we have nothing to do but hold our loved ones closely and say the final prayers, maybe a few million scientists developed spaceships for the evacuation of another million or so. The time comes. Earth smashes into Mars with a reverberation felt everywhere as we watch mars (with a diameter half the size of Earth) appear to sink into the earth. 7 billion people are obliterated in seconds, millions of years of artifacts, technology, and art are destroyed. Earth is now missing more than 3/4 of its original surface area, lava from the earth's core is flowing freely everywhere, destroying everything that survived. And the funny part is, the billions of tons of loose debris and rocks would fly in every which way, eventually catching up to and crippling the spaceships that survived in space, and eventually, they would destroy those first few ships who killed all of us in the first place.
(whoooo that was a long answer lmao)
