If Christ died on the cross for all of humanity

No, you're not entirely right. The Gospels in the New Testament are not opinions from the authors but rather they represent first-hand witness accounts.

They are testimonies depitcting the life and ministry of Jesus Christ. This is how we get all the quotes coming from Jesus as noted in their writings by these first-hand witnesses.

So these Gospels can't be catergorized as opinions from the authors. So its a form of evidence based on personal experiences.

Additionally, outside the Bible, Jesus is also mentioned by his near-contemporaries. Extra-Biblical and secular writers (many hostile) point to Jesus' existence, including the Roman writings of Tacitus, Seutonius, Thallus and Pliny, and the Jewish writings of Josephus and the Talmud. Gary Habermas has cited a total of 39 ancient extra-Biblical sources, including 17 non-Christian, that witness from outside the New Testament to over 100 details of Jesus' life, death, and resurrection

Biblical archaeological are not opinions but rather its the scientific study of the life and cultures of ancient peoples, as by excavation of ancient cities, relics, artifacts, etc.

The fascinating study has furnished background material for illustrating, illuminating and in many cases authenticating of the message and meaning of the Old and New Testament Scriptures. Archaeologists studying ancient civilizations by uncovering ruins and examining artifacts, are with increasing success confirming the accuracy of the Biblical texts.

Scientific discoveries like the big bang supports the claim that the universe had a beginning, likewise the second law of thermodynamics also supports this claim and so we know that the universe had a beginning.

So either the universe was popped into existence from nothing with absolutely no cause or the universe was caused to exist by something outside it. In chapter one of Genesis of the Holy Bible we read that "In the beginning God created the heavens and the earth"

So your argument in stating that my evidences are soley based on opinions is not a totally accurate one. Philosophical reasons are basicly opinions so you are right in regards to it being opinions.

So there are evidences outside of the bible, you have to do your research and seek them and don't just come to this thread thinking oneday somebody is going to hand over to you the concrete proof you seek...stop being foolish and start being realistic!
