Readers suggestions included the northern lights, reflections and genuine UFOs
Noise from the docks, aliens and reflections are just some of the theories ECHO readers have offered about mystery 'UFO' sightings.
Over four decades ago, the borough of Knowsley and parts of Liverpool were said to be visited by a wave of UFOs.
The unidentified objects, sometimes known as 'green flying saucers', have long been a source of mystery.
Alleged sightings stretch back years - and the ECHO reported some of the 'other worldly' sightings shared by our readers in the run up to Halloween.
A string of different theories have been offered by readers into the strange phenomena.
Di Ane wrote: "They always appear close to electrical pylons, which as we know are usually on the outskirts of the area, hence people saying they see them in open spaces ,where I think they recharge their crafts.
"[This] results in power cuts. Just my opinion, but its what I believe."
Kieran Grange added: "This is strange because I heard a weird buzzing noise outside my house on Sunday morning about 4am. I do live really close to the docks though and you hear all kinds of noises coming from there."
Craig Jones said: "I saw one of these years ago.
"[It] flew over the top of my work van, an emerald green ball about the size of a beach ball.
"[It was] fast. No sound [and] about thirty feet high. There were two of us [and] we both saw it."
Paul Bigley suggested it could be the northern lights, which are sometimes visible from the UK, although it's rare in the north west.
He said: "Possibly aurora borealis, AKA the Northern Lights. It has been known to be visible this far south."
Danny Lloyd Price put forward it might be something more everyday.
He said: "It’s the reflection of the indoor light against the window."
And Danny Shaw said: "It's 2020, I really wouldn't be surprised if this was actually a UFO."
In September one man was 'left puzzled' after seeing a strange object in the early hours of the morning in Prescot.
The man told the ECHO how he was at his friend's house when they spotted a strange green object floating in the sky, in the early hours of the morning.
Convinced it was a UFO he said: "It was only there for a few seconds and then it flew up into the clouds and went in the South East direction, towards Huyton and Halewood."
However according to one author "Knowsley is certainly no stranger to the baffling phenomenon."
