2007 odyssey, First time replacing a timing belt and I didn’t align the marks before taking out the timing belt. Is it ok to put the belt on and rotate the crankshaft? I don’t know what I’m doing so what should I do?

 

Rotate the cams and crank to the correct location. Just don't force the cams or crank. If you find a hard stop then stop! If it is the crank that stopped then turn the cams a little to change where the valves are. If it is a cam that comes to a hard stop then turn the crank a little to move the piston out of the way.

The pistons and valves can touch each other and if you force them you will bend a valve.

 

So just to make sure, this is done without a belt on right?

 

Correct no belt as you have already removed it while out of time.
