The Earth won’t be in any danger in our era’s soon, and we won’t be there to witness it. The aliens have bases in underwater lakes. We will not witness what they’ll be doing. But, it is not what most of you think. They are just here to check on us. They’ll be leaving our home planet, once the world comes at peace. They go to Earth from their home planets, and come back to their homes again. After that they come back to their bases here on Earth in underwater lakes. The mysteries are always pondering our questions of why they are here, and why won’t we witness what they’re doing. We mean no harm to them, but everything about aliens and UFO’s is so secret. So far we have discovered many things about them. Some scientists say that Earth will be in danger if they come here. My theory is they are here to make sure that things are okay and we are okay. I don’t think they will be harming us. I think space will do that to us, but in billions, and many billions years later. So, when they are here, there is no reason to push the red button. We don’t notice them coming here. We won’t ever see them in our lifetimes.
