Answer:
Well, according to Jesus, the gospel (which means, good news,) message that He preached is the coming Kingdom of God. He says that we should "repent of our sins and believe that good news message." (Mark 1:15)
So, going by that, I have to say, since nothing is recorded about Abel in that regard... I have to say that Enoch preached the Kingdom of God, first:
"...Enoch also, the seventh from Adam, prophesied of these, saying, Behold, THE LORD HIMSELF COMETH with ten thousands of His saints, to execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds which they have ungodly committed, and of all their hard speeches which ungodly sinners have spoken against Him." (Jude 1:14-15)
His audience sure wasn't very tolerant of the gospel, were they, that they killed Enoch over it? Those folks in the "days of Noah" were a tough sell. (Matt.24:37)
Answer
Adam was the first to preach the gospel to his own family. Though he could not see God he could commune with Him and so hear of the things that he should teach his family and his posterity.
Answer according to The Bible:
The gospel message could not be preached until the death, burial and resurrection of Jesus Christ. Because that is the good news. That God sent His son to die for our sins and be raised so we also can have a new life in him. So the first gospel message was preached by Peter on the Day of Pentecost and is recorded in Acts chapter 2.

Because Christians took the gospel to Rome. When the first gospel message was preached in Jerusalem there were people from many regions around the Mediterranean in Jerusalem to celebrate the festival of Pentecost. Many of these people believed the gospel and took the gospel message back to their home town undoubtedly some of these people were from Rome. You can read this in the New Testament Acts chapter 2, Act 2:5 And Jews were living in Jerusalem, devout men from every nation of those under the heaven.
