the reason for trench warfare was to take cover from enemy fire and motar shell fargments.
It was much easier to defend a trench because you were behing cover and camped in to your position unlike the attackers who were running across open plains and were constantly loosing men and getting shot down by machine gun fire.
During World War I, the phrase "going over the top" became emblematic of what ordinary soldiers experienced during the war and how the war as a whole was conducted. Literally, it referred to climbing out of a trench and facing the enemy -- while crawling over defense works, sliding under barbed wire, then making a dash for the enemy trenches while maneuvering past other defenses. More generally, it referred to taking on any challenge that exposes one to enemy fire or other dangers.

To protect themselves from enemy fire.
An advantage of a trench is that it was a line of security. Soldiers that were in trenches were able to see enemy soldiers and surprise them by force.
During WWI, in trench warfare, German armies dug holes in the ground that were 6 to 8 ft. tall, and wide enough that 2 soldiers could walk side by side at the same time! Trench warfare was fought by one group of soldiers advancing across no mans land to assault the enemy trench quickly, before returning to their trench to apply defensive fire on the enemy, who has retaliated by assaulting their trench. Then the enemy return once fire has ceased. Then they wait for the next move to be made.

Because as soon as you came out of YOUR protective trench to get to the enemies trench you would be machine gunned down.
