OK. Try this:
1. Turn the headlights on bright.
2. Have an assistant to try to crank the engine while you watch the headlights to see if (1) they go out or (2) dim severely or (3) remain bright.
3. If they go out, the battery is weak or the cable ends are dirty [this is the end at the battery, the starter, and the ground at the other end of the NEG cable. Or the starter is faulty.
4. If they dim severely (same as #3)
5. If they remain bright, you have a loose [bad] connection at one end of the battery cables unbolt the cables and clean the cable end and mounting surfaces.
Post your results here.
As a last resort; you'll have to try and turn the engine over by hand. To do this you'll need a breaker bar [aka pull-handle, cheater bar, etc] and a socket that fits the center crankshaft pulley bolt. Put the socket and pull handle on the bolt and turn the engine in the direction which would tighten the bolt. Be sure to rotate the engine two complete revolutions. You can try rotating it in the others direction [it should go that way as well]. However, if the bolt starts to uncsrew tighten it back up and just be satisfied that it turned in the other direction - that was good enough).
If you can turn the engine by hand, the starter should be able to turn it easily.
Now, If all that is done and it still will not spin over; a faulty starter is the likely suspect. You'll have to remove it to have it tested (but only is necessary).
