A British scientist claims to have discovered alien creatures at an altitude of more than 40 km in the stratosphere.

Professor Milton Wainwright of the University of Sheffield said the alien creature was discovered in the stratosphere, the furthest distance an organism has ever been found outside of Earth. Test results show they are six times larger than the size limit for a particle that can be levitated from Earth at this altitude.

“We sent balloons and a sampler aloft, but detected no pollen or grass, no pollution, and the air was completely pristine. These organisms have a certain structure and are not related to each other. regarding creatures on Earth,” Express quoted Wainwright as saying. The creature made a small impact on the sampler and that’s why he believed they came from space.

Professor Wainwright’s statement was revealed after a student published a letter announcing the discovery on Reddit. Previously, Wainwright had announced the discovery of microorganisms, possibly a type of microalgae, at an altitude of 26 km above Earth’s level in 2013.

While many scientists think that there is not enough convincing evidence, others believe that Wainwright was completely wrong. But if proven authentic, his discovery could change what people know about the origin of life on Earth.
