The Bible does not state how old Adam was when he had his first son Cain (Genesis 4:1) as well as his second son Abel (vs. 2). The Bible also doesn’t give the age of Adam when he had other sons and daughters (Genesis 5:4). The Bible only states that Adam was 130 years old when he had his son Seth (Genesis 5:3). Seth was born later to take the place of Abel because he was murdered by Cain (Genesis 4:25).
Adam indeed followed the command to be fruitful and multiply (Genesis 1:28) well before 130 years had past.
