Are aliens real?

Most recently, scientists announced that they discovered possible life on Venus, Earth's closest neighbor in the solar system. In the clouds above the planet, a group of astronomers from all over the world found traces of a chemical only created by living beings.

According to the Washington Post, the chemical is called phosphine. Traces of phosphine that appear in Earth's skies are directly linked to human activity, scientists say.

However, that's not a guarantee there's aliens living in the clouds above Venus. To be sure, NASA and other scientists that study space will have to send a spacecraft to explore the planet's atmosphere.
