Oh noo... Dont.. please dont say sun if flat too...
There must be atleast 1 single brain cell left in there 
THE SUN IS NOT FREAKIN FLAT...
Its against any laws of physics.. just .. omg... the amount of stupitidy... how can it be... 
You know what.. maybe there is no sun up there.. i think its a giantic flashlight floating above the earth... yeah. that sounds more logical.
Here's something to think about. If you shine a torch light at the sky, you know, like the batman signal. Is it a globe or is it flat or does it just appear like it's either one when in fact it's simply a hologram or reflection. What do you think?
thats not because there is any magic involved.. its the dust and the gas in the air reflecting the light which causes it to look like a beam... try this: go into a dark dusty room and turn the flashlight on.. you will see dust shining everywhere because its reflecting light.
You asked why the sun is a spotlight. I've just told you. If you think it's a big ball of nuclear fusion at 93 million miles away in space and over 850,000 miles in diameter, then you go right ahead.
Don't expect me to share in that. I'd sooner believe it was a glowing dog turd on a string than believe that absolute crap about what we're told.
A torch light and the sun are two different things, firstly, and secondly, nuclear fusion cannot be sustained by a body without a circular form arising from the attractive energetic forces created by said fusion
Nuclear fission and fusion are imaginary things that us poor second class citizens have been coaxed into accepting.
Really? That's why nuclear waste is around, why things are radioactive, why nukes were dropped on and decimated the potential for life in Hiroshima and Nagasaki for years, and why you can view gamma radiation?

You have no evidence to support your claims, yet I could support mine with a jar, some water, an outlet, and then a dual pronged metal rod
