This is a list of alleged sightings of Aliens or UFOs in Croatia.
Aliens are any living creatures that are not originally from Earth. They could be anything from intelligent life to simple bacteria; however, there was no concrete evidence to support life outside of our planet as of now. Scientists had allegedly found in an asteroid what could be Martian bacteria
There was an UFO seen over a town of Lajkovac, Croatia. Croatia was a part of Yugoslavia at the time and Josip Broz Tito (a Yugoslavrevolutionary and statesman) was seen in Lajkovac and UFO was later not found. It`s said that UDBA (State Security Administration) and Tito were hiding an dead alien and experimented on him. Some pictures leaked that look quite convincing.
