Epiphytes in their natural habitats are often found growing from rocks, trees, or suspended in the air. Epiphytes absorb most of their nutrients from the air and surroundings. Epiphytes like orchids do not have prominent roots in the soil, so these aerial roots may be necessary to provide your plant with what it needs to survive. You can try turning the aerial roots inwards towards the soil if possible but try not to cut them if at all possible.
