What do you do when the BUCKS are comming through at 5:30 am in the pitch black??

So I was in my stand this morning at 5:15 am my friend went down the corn field about 200 yards away & set up his ground blind in the tree line he got all set up got in his chair & not 10 minutes later he spots a outline of a buck not 10 yards away nice 8-10 pointer he said so he goes to stick his bow out the window & as he lines it up he looks through the scope & its just to dark so he looks over the scope & as he does that theres another 12-14 pointer buck not 4 ft in front of his blind he said he could have touched it it was so close , but when he stuck the bow out the window it spooked the the one that was so close & it jumped & took off he didnt even see that one walk up to him ,then the second one spooked & made some crazy scream/grunt noise twice & TOOK OFF , im telling you guys I got down around 9:30 AM & walked over to him & the hoof prints were SO DARN CLOSE it was amazing , he asked me did you see them I said see what all I heard were these crazy weird noises he said that was the deer. I HAVE YET TO SEE ANY DARN DEER THIS YEAR .

So we walked the tree line down the corn whichhas been cut , & there are scrapes under every over hang big scrapes theres buck poop , hoof prints the scrapes are fresh also .there are about 4-5 Acorn trees down this line .

So my question is what should I do here please help .Will these Bucks come back through there does this sound like a mating area im new to all this .
