Sure sure, next you’ll say birds are real!
Not across oceans though. Earth is curved.

Come off it, nobody’s saying that.

I know, what if we put lasers on the birds!

Not just curved, but curved quite substantially, despite what your eyes may tell you. At eye level on a flat plain you can only see about 3 miles due to the curvature. The closest points across the Atlantic are 1,770 miles apart.

At 10 meters, line-of-sight is over 10 km.
On a jet traveling at 1 km, line-of-sight is over 100 km.

We’ll just curve the lasers then.

Even without curvature, there’s way too much atmospheric interference for that. Laser communication works well in space where there is literally nothing in the way, including ajr. Even point to point microwaves only kind of work on earth.

Some short waves seem to be good a penetrating clouds, so some transmission is possible.
