Pigs are like humans in that they are omnivorous mammals (something very unspecific!) and have similar meat (which follows from the previous point), are social and relatively intelligent… and I think that’s it. I assume you also include that many domestic breeds have sparse fur and/or pinkish-beige skin similar to humans from Northern European, but this is not so applicable for the wild boar, other suids and even many other domestic breeds, including old ones that used to be much more common.
Meanwhile, there are many rather drastic differences between humans and pigs - for the most obvious, humans are plantigrade bipeds with five nail-bearing digits on both hand and feet, including the inner digit being specialised, whereas pigs are ungulate quadrupeds with symmetrical four-toed feets, walking on the inner pair of hooves while the outer toes are vestigal.
On the other hand, humans blatantly are apes. They look almost exactly like the other apes and especially chimpanzees and bonobos, just with modified spine, hips and feet as specialisations for obligatory upright walking (something all apes are capable of and use under certain circumstances; note also the similarities to knuckle-walking and in sitting posture) - of note, the big toe is a vestigal thumb, lacking the mobility but still rataining the distinctiveness compared to the other digits and reduced fur.
