Answer:
I am a shower that lights up the sky
I am in the past never in the future. I don't exist but have existed. I saw what you saw and that is what I will ever see.
I touch the Earth, I touch the sky, but if I touch you, you’ll likely die. What am I?
lighter than feather and softer than silk yet the strongest man in the world cannot hold me for more than a few minutes.
You can catch me but cannot throw me.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
