If your timing belt came off when the motor was running, there 2 possible scenarios:
Motors are interference (pistons hit valves if motor spins <=2 revolutions without a functioning belt/chain) or not.
1. if kia 1.8 motor is an "interference" engine ... major damage already occured, at best valve stems are bent and you have to pull the head to install new valves, at worst, a piston now has a hole in it and you get to do a full rebuild. I'm now praying for you;~).
2. if it's not an interference engine ... joy is you, you rotate the cams whichever way you want and pistons do not hit valves ... and as they say in England "Bobs your uncle" ... ask a Brit.
I'm guessing that Kia doesn't build an interference motor with a belt ... the dealer or any shop with access to a good paid automotive database can tell you if the motor is interference or not.
The standard explaination for rotating forward ... which is not necessarily clockwise, has to do with tensiong the belt and how you get the tensioner in the correct position to do its job ,,, which is to keep the timing belt from jumping teeth. Each motor can be slightly different for tensioning the belt, so you need the specific instructions for your year car with the 1.8 motor. If the manual says you need special Kia tool "XYZ" ... get it or an close equivalent, don't try to use a pair of vicegrips clamped to a screwdriver.
You need to spend $20 for a Haynes manual for your car. Now you or I might think for a minute that what they say in the haynes manual isn't the easiest way ... but then we would probably be wrong.
Having done several timing belts, engine rebuilds and general maintenance over the years ... I can tell you this sincerely ... advice from someone (haynes in your case) who has actaully done the job you are embarking on is worth more than $20 if you are doing a job that takes more than a couple of hours. The specific stepwise instructions they have will get you successfully to the place where you have a new timing belt and the motor runs right by the shortest path. And one of the biggest benefits in doing a job of any complexity, it that you have written stepwise reassembly procedure documented ... so you don't end up at step 17 in the reassembly ... just to realize you didn't do step
9 .. that now requires to take stuff apart for the second time !^%$@!
Good luck ... you'll feel great when the thing is purring again.

there is a little mark on the crankshaft which you line up with the 'o' mark on the casing ..
remove the cam cover and look at the cam you should see a nob on the cam about 3 th lob and that should be facing just left of the engine ..
if you have a turbo there is two notchs on the injection pump pully ..if turbo there is a 't' mark on the rear of the cover the notch on the pully should mark up with the 't'..
the timing is set..

There should be plated links on those chains too. There is an index dot in both cams on each head that set at the twelve o'clock position.

Belt covers need to be on. Timing mark on crankshaft (while on compression stroke) should line up with TDC mark on cover. then Camshaft mark, needs to line up by looking through access hole of cover, and align mark on cam sprocket with pointer on inside of belt cover.

Yes be sure the number one piston is at TDC firing stroke or compresson stroke and line up the timing mark pointer is pointed at exactly zero. One more thing when aligning the camshaft sprocket or sprockets be sure that when you are rotating the sprocket for the cam it is rotating in the correct direction and also be sure you observe the intake valve for number one shutting as you bring the marks up to alignment points, the intake valve and the exhaust valve should be shut when the marks line up if not you could have the cam sprocket off 180 degrees, get it right the first time or you may damage a valve trying to start.
