if he put his faith in Jesus Christ He did (Yes, old testament [people had to put their faith in the coming ‘Redeemer’ which was Christ). Eve exhibited faith in God after being expelled from Garden- so it is very likely she and Adam were saved- In Genesis, We’re told Adam and Eve- after eating the forbidden fruit, met the LORD in the garden- many believe this was Christ the LORD- who made atonement for them by sacrificing an animal to cover their sin
Do we know for sure? No- but it’s highly likely they did go to heaven
Exactly right. Thank you.
