Ball&boomerang shaped craft in Merseyside

I have been noticing a lot of strange things lately,but i will tell you about tonights episode.......................................................................................................................Firstly i witnessed two extremely bright lights in the west skies approx 10miles away and 2-3,000ft up.These lights then became one as they merged,then it illuminated and became an arc shape convex consisting of a number of lights with the centre one being much brighter than the rest,i'd say about 7 lights in a vertical arc.I would say the arc diminished within 20 seconds with half of that showing clear lights.It looked very alike a type of eclipse.I then noticed very high up in the south west two bright yellow/orange balls travelling north/westerly in tandem and at constant speed.Within a couple of minutes i noticed a bright light travelling on the same path but in the opposite direction,but this was travelling at a variable speed & seemed to be dipping up & down minimally in travel.Then within another few minutes i saw a blue craft in the shape of a swallow/swift,boomerang or chevron,coming from the south west direction travelling at great speeds,a few miles in split seconds.It travelled in an "S" shape carrying out 180degree turns easily.It proceeded to fly east,towards me in the same S pattern and flew over my row of houses at about 200ft and was gone within approx 7 seconds.Then within seconds another identical craft,again doing 180degree turns at great speeds came from the exact same direction but went south before it reached me.To my astonishment Two more turned up,same type,blue lights,from the same direction,same speeds but were flying extremely close together,20ft apart i'd say & were flying as if they were being controlled by the one command simultaneously.They were travelling differently to the other two.These were travelling at a reduced speed and in a weave pattern & possibly angled towards earth,as if reducing height as they both flew over me & away out of sight.I then,after a short time,proceeded to exit my house from the front to see if i could catch another glimpse and sure enough the pair were virtually above my head travelling at a much slower speed at about 200ft & travelling from the East in a South Westerly direction.
