Because DNA is identical, and it is the unique genetic code from which we each emerge. With twins - DNA is the same, as are the chromosomes, but the proteins, cells and organs which are transcribed/expressed from that DNA may vary slightly.

They are identical because they share the exact same genes/chromosomes from both parents. When the zygote split in half, both halves got the same amount.

Identical twins are essentially clones produced by nature, so they have the exact same genome.
