Do aliens exist? I・ve also been thinking the same question over the last couple of weeks. Some people have stories saying they DID see an alien before. I・ve also seen a few videos of people who claimed to see aliens online before. A few videos said that they had a seen an alien crossing the road. The first video showed some creature with a big head crossing the road at night, but it was too fast, so no one could capture it. At first, I didn・t really understand the second video, because I didn・t see any alien, and I realized it was some slow moving object crossing the road, but if it was an alien, why didn・t the person catch it? The alien actually was a tortoise, in my point of view. But my sister believes in aliens, because who knows? Maybe there could be another solar system besides ours? It is a real mystery weather extra terrestrials are real or not. It was said that in the 1900s men sent a probe beyond Pluto carrying a picture of a naked man and naked woman and a picture of the solar system. Because the probe can・t transmit pictures to Earth, if the aliens find the probe, they will find out where we live, how we look and that stuff. But suppose the aliens are unfriendly, and they will invade our planet?
