So what I’m reading is that these gas absorb the light from the sun and keeps it trapped on the earth.
What I don’t get is how is it letting the light and heat in from the sun in, but not the light and heat reflected from the Earth out? If it’s a barrier, shouldn’t it block both ways? If it’s not a barrier, how is it trapping the heat?

Imagine that barrier as having two different surfaces, one of them is more reflective than the other, lets say a sunray hits the ozone layer 40% of that makes it through and hits the ground, then the ground reflects it and it bounces up again this time only 40% of that 40% actually makes it out, creating a cumulative effect, look up how a greenhouse works
