I went off the curb and heard something hit hard underneath and oil leaked out everywhere then engine shut off

I went off the curb and heard something hit hard underneath. Got to the place about 6 to 8 miles away oil light was on. Saw a trail of oil and a puddle in the front of car. On way home I stopped and put the quart of oil I had in. There was only about a 1/2 in of oil before I put the quart in. Also the oil cap would not come off and I had to force it off. So about 3 or 4 miles the car shut off. No smoke no sound I put more oil in 2 quarts car would not turn over. The cop said oil was on the hood on the inside. Had it towed home and went out and I think the oil pan bolts are loose and lots of oil everywhere. I did not notice oil when I put the first quart in. So do you think it quit from the oil flying all over the engine? I hope it was the oil pan that is close to the ground. Also the car seems closer to the ground under the hood.
