Mark 16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
I say that this verse is not a genuine verse of the Bible because most ancient Copies of the scripture especially those that are 1st,2nd,3rd,4th century does not contain Mark 16:15 will you preach the gospel to the birds,fishes in sea or the dogs
Romans 1:23-25 And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:
Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
The word creature those not only mean human being it implies that Apostle Paul is talking about creature which are not human being to preach to every creature meaning to approach them one by one that is a sperious verse its contradict the real verse in the Bible
Matthew 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
Particularly men preach to nation not to all creature preaching the gospel to creature then you are preaching to birds,fishes in the sea .I have gone preaching the gospel on radio,television,satelite broadcast because I do not know if I will live a long year .I want to value the Bible so mark 16:15 is not part of the Bible it's an addition to the Bible.
