We think they might be, and here is why.
In 1977, two researchers named V. Alexandrov and G. Seliverstop, were in a submarine at a depth of 4,000 feet below the surface of Lake Baikal.
After they turned off their spotlights to explore the length of sunlight penetrating into the water, the scientists were bathed in light from a strange glow.
It was so like if our device was lit from above and the side by two strong spotlights. Only a minute later, unknown floodlights went out, and we found ourselves in total darkness” – V. Aleksandrov
Vyacheslav Lavretevich, a local lifeguard, recalled a similar incident.
We were on a yacht on Lake Baikal, and from under us flew out a huge glowing disk. It blinded us, and for a second flew into the sky.
We did not even have time to grab any cameras, although many of us saw it. It was huge, and lit up all of our yacht. It was probably 3,000 feet in diameter, a huge disk.
For three minutes it shone from below, and then abruptly departed in a second. The spectacle was huge, awesome, beautiful and shocking.”
Oleg Chichulin was also on a boat with his students. They all witnessed strange objects submerging into the lake:
There was a ball that glowed. And then this ball started to fade, and blush, and it turned into a red ball. This red ball lay on the water for a while, and then began to sink. And all this gradually went under water, and it became dark.”
In addition to the UFOs, there had been encounters of underwater aliens, wearing masks similar to our spacesuits.
As described by Alexey Tivanenko, a doctor in history, in 1982, a group of seven military were at a depth of about 160 feet when they met swimmers, around three meters tall, dressed in tight-fitting silvery suits. They didn’t have any scuba or other apparatus, only helmets on their heads.
They were ordered to capture the strange beings, but they were surprised by some sort of flashing ray and washed ashore having signs of decompression sickness.
After this encounter, three of the seven military died, as one of the decompression devices they had was broken. Tivanenko shared some petroglyphs and images representing the aliens, all united by the same characteristics: tall beings, dressed in flashy suits, all with the helmets on their heads.
Besides this descriptions of strange encounters at Lake Baikal, there are countless others including some from the Russian folklore.
Once again, the mysterious craters from Siberia might be made by some sort of mechanism or even an UFO, as there is no reasonable explanation of another sort.
They might be breaches into the Earth’s crust, leading to the sacred ground of Shambala or the Inner Earth, the sacred place described by so many.
