It’s obviously round first piece of evidence is the countless accounts of people in space stating it is round, and you’ve got to think about it. Why would they lie and create this international conspiracy? What would be the point in saying the earth is round when it’s flat?

The anatomy of sponge which causes water to flow through it is the poriferan ventilation general anatomy.
Sponges do not have nerves or muscles and they do not move their only way which is relying on water flow in order to remove movement of sperm, remove gas exchange, remove wastes, and bringing food.
Because of architecture of sponge and action of choanocytes then the flow of water is being utilized efficiently by the sponge.
Water flows to spongocoel and to sponge through small openings which are found in the sponge, and out of sponge through Osculum which are the large openings.
