The '''distant past''' was that period which was historically remote to [[the Doctor]]'s usual travels. It had no exact date range, but could be considered to extend from the [[Big Bang]] (and perhaps earlier) to the development of modern [[human]]s, in about 100,000 [[BC]]. The [[Dark Times]] of [[N-Space|the universe]] were known to have occurred in the distant past.

== Beginning of the universe ==
*'''Beginning of time''': The [[Event One|Big Bang]] occurs due to a combination of at least two events: an ejection of fuel from the leper ship ''[[Terminus]]'' ([[DW]]: ''[[Terminus (TV story)|Terminus]]'') and the explosion of the time ship ''[[Vipod Mor]]''. ([[BBCR]]: ''[[Slipback]]'') On at least two occasions the [[the Doctor's TARDIS|TARDIS]], through malfunction or interference, has attempted to return to this point in time, which is also known as [[Event One]], only to be prevented from doing so.

At the beginning of time, the [[Event One|Big Bang]] occurred due to a combination of at least two events: an ejection of fuel from the leper ship ''[[Terminus]]'' ([[TV]]: {{cs|Terminus (TV story)}}) and the [[explosion]] of the time ship ''[[Vipod Mor (Slipback)|Vipod Mor]].'' ([[AUDIO]]: {{cs|Slipback (audio story)}}) This occurred on [[13 February]], [[BC|13,500,017,093 BC]], at 11 [[am]].

([[AUDIO]]: {{cs|The Nowhere Place (audio story)}}) [[The Doctor's TARDIS|The TARDIS]] attempted to return to this point in time, which was also known as [[Event One]], only to be prevented from doing so. ([[TV]]: {{cs|Castrovalva (TV story)}}) The first [[star]]s and [[planet]]s were formed in the aftermath of the explosion. Life evolved and civilisations arose on many worlds.

*''' 4 billion B.C.E.''': The last [[Jagaroth]] ship explodes on primitive [[Earth]]. The explosion kills the crew and splinters [[Scaroth]] into 12 sections in [[Human]] history. The explosion also causes the development of life on [[Earth]], meaning that to prevent the explosion would leave the planet a desolate rock. ([[DW]]: ''[[City of Death]]'')

The distant past was that period which was historically remote to the Doctor's usual travels. It had no exact date range, but could be considered to extend from the Big Bang (and perhaps earlier) to the development of modern humans, in about 100,000 BC. The Dark Times of the universe were known to have occurred in the distant past.

Beginning of the universe[[edit] | [edit source]]

At the beginning of time, the Big Bang occurred due to a combination of at least two events: an ejection of fuel from the leper ship Terminus (TV: Terminus [+]Loading...["Terminus (TV story)"]) and the explosion of the time ship Vipod Mor. (AUDIO: Slipback [+]Loading...["Slipback (audio story)"]) This occurred on 13 February, 13,500,017,093 BC, at 11 am.

(TV: Castrovalva [+]Loading...["Castrovalva (TV story)"]) The first stars and planets were formed in the aftermath of the explosion. Life evolved and civilisations arose on many worlds.

On Planet One, the oldest planet in the universe, River Song carved a message for the Doctor in a diamond cliff. (TV: The Pandorica Opens [+]Loading...["The Pandorica Opens (TV story)"])

The Grey Man's race observed as the first humanoid race destroyed themselves in bacteriological warfare. In response, the Grey Man created Cathedral to introduce uncertainty to the concept of duality which his people had imposed on the universe.

According to one account, the year 10,000,000,000 BC was at the "dawn of human civili[s]ation". During this time, the Eleventh Doctor accidentally started a galactic space-war that changed the course of human history every time something blew up. This caused radical changes in the 21st century, such as humans changing species before the timeline was set right again. (COMIC: Short-Change [+]Loading...["Short-Change (comic story)"])

According to another account, the Earth formed in the solar system around 6,000,000,000 BC. The Eleventh Doctor photographed what would be the site of the Caliburn House as part of his investigation of the Caliburn Ghost. (TV: Hide [+]Loading...["Hide (TV story)"]) However, the Tenth Doctor claimed he went back "4.6 billion years" from 2007 at a point to when there was "no solar system. Not yet." The Doctor and Donna Noble saw the Secret Heart, a Racnoss spaceship hiding from a war and entering what would become the solar system as the Earth began forming around it. (TV: The Runaway Bride [+]Loading...["The Runaway Bride (TV story)"]) At the same time, the Sentience was trapped inside the forming Earth, underneath the area that would later be known as Crook Marsham. (PROSE: Nightshade [+]Loading...["Nightshade (novel)"]) According to one account, the Moon left the Cthalctose homeworld around 6,000,000,000 BC and eventually entered the solar system.
