This round cloud in the photo is more than it seems. Its actually a UFO that has created the cloud around it to hide from human eyes. Aliens do not wish to cause alarm or panic for humanity so they must hide from us. This ship is over an old volcano which very well could have an underground alien base below it about 4-6km down. Aliens want to come close, they have work to do, bases to visit, intel gathering on humans to do, so coming as close as possible to the ground is often essential. Created a cloud around the UFO is a logical and intelligent way to hide from humanity and keep the status quo. 

I've been to Bali island once. Its a culture thats seems like you stepped one hundred years back in time. Its amazing, beautiful, peaceful with ancient temples all over the place. Even the locals often bath in the running water near the roads. I met a man there who had five wives, all working while he relaxes. Very strange and unique culture. I could see why aliens would want to visit here. Less alien believers and more god believers here. Perfect place to come and go unnoticed in UFOs hidden in clouds.
