I think I found out how to time travel in the past and future?

See there maybe wormholes out there that have already been created millions of years ago by aliens and so thats how aliens are able to travel far distances to visit Earth and back to their home galaxies which may be millions of light years away, hence the years of reports of UFOs even back to the ancient times. These wormholes if we find them will allow us to travel back million years in time or as far back as the time the wormhole was created. So we can travel back any time period within a million years, whether it be 100 years ago, 1000 years ago, or 100,000 years ago. Thats the only way aliens are visiting us from long distances because they have created wormholes millions of years ago. Our job is to find these wormholes.
