Because all fetuses start off as females until the testosterone surge kicks in around the 3rd or 4th week of development. The nipples have already formed by then.

Without Nipples the Male Chest Looks Strange! The nipples provide a focus point for the male chest. They direct the eye to the curve of the pectoral muscle.
Men and women are mammals (from the Latin mamma breast) a species that have breasts and feeds its young with milk. The human embryo has tissue that will evolve into breasts. Both male and female babies are born with nipples and ducts intact. It is the presence of genes that direct hormones to differentiate the breast tissue. The Y chromosome stimulates hormones such as testosterone to form male features.
Insufficient or defective testosterone, poor tissue responsiveness, or an unbalance of other hormones like Estrogen and Prolactin can cause female like breasts even in men (Gynecomastia). At birth, the small amount of the mother's estrogen in the baby can result in small breasts that usually resolve. There can be an inbalance of hormones during male puberty that can result in temporary breast growth, which for most resolves. There are many medical problems and drugs that can cause male breast growth.
The nipple is actually the central protrusion inside of the pigmented areola. There is a thin muscle just under the skin that when stimulated, tends to flatten the puffed male nipple areola. This muscle when stimulated in a breast feeding woman, projects the nipple for the baby. Nerves that innervate the nipple / areola can produce pleasure for both men and women.
The male chest without nipples has an unusual look - move your cursor over text or nipples. Dr. Bermant did not remove the nipples from this bodybuilder. This picture is after surgery to sculpt the previously deforming gynecomastia. Men's nipples and areola that are puffy can distort the male chest profile. Long nipples can also be a problem.

Because Nipples Aren't Sex Related Parts of the Body. Another explanation is that when babies are created they are asexual, and then later on in the gestation period, they are determined to be male or female.
There is a hilariousss book called "Why Do Men Have Nipples?" that has a bunch of different questions such as those.

Nipples are sexy, fun and they would look weird without them. They compliment a hot body perfectly.

Because they are mammals. All male mammals have "superfluous papilla" (useless nipples.) I guess God just recycled the template with a few minor changes.

Because even though men have XY chromosomes, they still have one of the female Xs, thus titties.
